Product information

Product description
The ProcartaPlex™ Human Simplex and Combinable Panels have been optimized for detection of multiple analytes from serum, plasma, and cell culture supernatants. Additionally, some assays were validated with urine, cell lysates, or cerebrospinal fluid (CSF) samples.
ProcartaPlex™ Human Simplex and Combinable Panels are designed to be combinable with each other so that you can create your own multiplex panel that utilizes Luminex™ xMAP™ technology for protein quantitation. When combining multiple Simplex Kits only one buffer kit (Basic Kit) is needed for each assay plate regardless of plex size. The buffer kits are sold separately and are optimized for the differ ent species and kit formats. When combining Simplex Kits with Combinable Panels Kits, there is no need to purchase a buffer kit. All buffers are included in the Combinable Panel Kit.

Procedural guidelines

• Thoroughly read this user guide and the Certificate of Analysis that is included with the assay kit. A product insert may contain specific instructions for proper use of your kit.
• For FLEXMAP 3D™ and INTELLIFLEX™ instruments initiate the startup protocol to warm up the lasers for at least 30 minutes. Ensure that the Luminex™ machine is calibrated according to the manufacturer’s instructions.
• When working with samples and standards, change the pipette tips after every transfer and avoid creating bubbles when pipetting.
• During the incubation steps, cover the plate with the Black Microplate Lid provided in the kit to minimize exposure of the beads to light.
• Be careful not to invert the plate during the assay or allow contents from one well to mix with another well.
• Use a multi-channel pipette and reagent reservoirs whenever possible to achieve optimal assay precision.

Competitive assays
Competitive assays are based on competitive ELISA technique and require addition of Competitive Conjugate Solution (1X) to samples, standards, and blanks. Competitive assays available are listed below:

Methods

Prepare the samples
Thaw frozen serum, plasma, and urine samples on ice and mix well by vortexing. Centrifuge at 10,000 × g for 5–10 minutes to pellet out particulates. Avoid multiple freeze/thaw cycles. If samples are high in lipid content, centrifuge at 10,000 × g for 10 minutes and transfer contents to a new tube.

Prepare plasma samples

1. Collect samples in sodium citrate or EDTA tubes. If using heparin as an anticoagulant, no more than 10 IU of heparin per mL of blood collected should be used to prevent assay interference that can result in a false positive signal.
2. Centrifuge samples at 1,000 × g at 4°C for 10 minutes within 30 minutes of collection.
3. Collect the plasma fraction. Use immediately or store aliquots at –80°C.

Prepare serum samples

1. Allow blood to clot for 20–30 minutes at 20–25°C.
2. Centrifuge at 1,000 × g for 10 minutes at 20–25°C.
3. Collect the serum fraction. Alternatively, a serum separator tube can be used following the manufacturer’s instructions.
4. Use immediately or store aliquots at –80°C. Avoid multiple freeze/thaw cycles.

Prepare cell culture supernatants

1. Centrifuge samples at 1,400 rpm for 10 minutes at 4°C to remove particulates.
2. Aliquot the clarified medium into clean polypropylene microcentrifuge tubes.
3. Use immediately or store aliquots at –80°C. Avoid multiple freeze/thaw cycles.

Prepare CSF samples

1. Centrifuge samples at 1,400 rpm for 10 minutes at 4°C to remove particulates.
2. Use immediately or store aliquots at –80°C. Avoid multiple freeze/thaw cycles.

Prepare urine samples

1. Centrifuge at 1,000 x g for 5–10 minutes at room temperature to remove particulates if needed.
2. Aliquot the clarified medium into clean polypropylene microcentrifuge tubes.
3. Use immediately or store aliquots at –80°C. Avoid multiple freeze/thaw cycles.

Prepare cell lysate samples
For preparing cell lysates, we recommend that you either use ProcartaPlex™ Cell Lysis Buffer (Cat. No. EPX-99999-901) or Invitrogen™ Cell Extraction Buffer (Cat. No. FNN0011) supplemented with 0.5M EDTA and Thermo Scientific™ Halt™ Protease and Phosphatase Inhibitor Single-Use Cocktail (100X) (Cat. No. 78440 or 78442). For example, add 100 μL of 0.5M EDTA Solution and 100 μL of Halt™ Protease and Phosphatase Inhibitor Single-Use Cocktail (100X) to 9.8 mL of Cell Extraction Buffer. Depending on your cell system other buffers can be suitable as well.

1. Stimulate cells as desired.
   a. Non-adherent cells:

   • Collect the cells by low speed centrifugation (400 × g for 10 minutes at 4℃).

   • Remove the medium from the pellet, and wash twice with ice-cold PBS by low speed centrifugation.

   • Remove the PBS, and add 0.5–1.0 × 107 cells/mL Cell Lysis Buffer yielding about 500–3000µg/mL protein according to BCA test.

   • Incubate on ice for 15 minutes, vortexing every 5 minutes.
     b. Adherent cells:

   • Remove the medium from the cells, and wash twice with ice-cold PBS.

   • Remove the PBS, and add Cell Lysis Buffer to cover the surface of the culture dish.

   • Incubate on ice for 15 minutes, vortexing every 5 minutes.
     Note: Alternatively it is possible to trypsinize, wash and lyse adherent cells as described for non-adherent cells.

2. Collect the cell lysate.

3. Transfer the lysate to a microfuge tube, then centrifuge at 13,000 rpm for 10 minutes 4℃.

4. Aliquot the cleared lysate into clean microfuge tubes. Then determine total protein concentration.

IMPORTANT!

• Proceed to analysis immediately after collection or freeze and store the cell lysates at –80°C.
• Avoid multiple freeze-thaw cycles of the frozen cell lysates. Thaw completely, mix well, then clarify by centrifugation at 18,000 × g for 5 minutes before analysis to prevent clogging.

Dilution of serum and plasma samples
You may need to further dilute your samples if the analyte concentration exceeds the assay upper limit of quantitation (ULOQ). When preparing dilution of serum and plasma samples, use Universal Assay Buffer (1X). For dilution of cell culture supernatant samples, use cell culture medium that was used to culture the cells. Recommended dilution factors for analytes with high normal serum or plasma concentration are listed in the Table 1.
Simplex kits for analytes with high concentration in serum and plasma include Universal Assay Buffer (10X).

Dilution of CSF samples
You may need to further dilute your samples if the analyte concentration exceeds the assay upper limit of quantitation (ULOQ). When preparing dilution of serum and plasma samples, use Universal Assay Buffer (1X). For dilution of cell culture supernatant samples, use cell culture medium that was used to culture the cells. Recommended dilution factors for analytes with high normal serum or plasma concentration are listed in Table 2.

Table 2   Human analyte dilution factors for CSF samples

Dilution of urine samples
The assays for the analytes listed in (Table 3) are validated for the use with urine samples. These targets typically have high concentrations in urine samples. We recommend that you dilute samples 1:100 in Universal Assay Buffer (1X) to ensure that they fall within range of the assay.

Table 3   Human analyte dilution factors for urine samples

Analytes| Recommended sample dilution factor
TIMP-1| 100
Uromodulin| 100

Dilution of cell lysates samples
ProcartaPlex™ Signaling Assays are validated for the use with Cell Lysates. Please refer to “Prepare Cell Lysate samples on page 10” for sample preparation. We recommend that you dilute samples 1:5 in Universal Assay Buffer (1X). Higher dilution might be necessary depending upon cell-lysates used.

Recommendations for isolation and lysis of exosomes
After isolation of exosomes by precipitation with reagents—Total Exosome Isolation Reagent (from serum) Cat. No. 4478360, (from plasma) Cat. No. 4484450, or (from cell culture media) Cat. No. 4478359—ultracentrifugation, or other procedure, lyse exosomes using Exosome Resuspension Buffer provided in the Total Exosome RNA & Protein Isolation Kit (Cat. No. 4478545) or other established procedure.
Further dilute the sample in 1X Universal Assay Buffer if needed, then immediately proceed to add samples to the plate.
Resuspension volume and predilution, if needed, depends on the exosome source, volume, and sample concentration.

TGF-β (acidification of samples)
TGF-β1 has to be acid treated for proper detection of the bioactive form. Therefore, this analyte should be tested as simplex assay. An additional datasheet with the preparation instructions are included in TGF-ß kits and can be requested from technical service.

Prepare the reagents
Before starting with the assay protocol, define the plate map. Mark the standard, sample, and background wells to determine the number of wells used (see Appendix A, “Recommended plate layout”).

Prepare 1X Wash Buffer
Bring the Wash Buffer Concentrate (10X) to room temperature and vortex for 15 seconds. Mix 20 mL of the Wash Buffer Concentrate (10X) with 180 mL ddH2O. Mix gently to avoid foaming. Wash Buffer (1X) can be stored at 2–8°C for up to 6 months.

Note: Additional Wash Buffer Concentrate (200 mL, Cat. No. EPX-66666-001) can be purchased separately for automated plate washers.

Optional: Prepare 1X Universal Assay Buffer (UAB)

IMPORTANT! This dilution step is only required for kits containing 10X Universal Assay Buffer.

Note: 1X UAB is required for the preparation of standards and dilution of serum and plasma samples, CSF and cell lysates only. If working with cell culture supernatant samples, use the cell culture medium as a diluent.

Mix 10 mL of 10X Universal Assay Buffer (UAB) with 90 mL ddH2O. Mix gently to avoid foaming. 1X UAB can be stored at 2–8°C for up to 30 days.

Prepare 1X Competitive Conjugate Solution for competitive assays
Competitive Conjugate Solution (50X) is included in Competitive Assays. Prepare the Competitive Conjugate Solution (1X) by mixing 50 μL of Competitive Conjugate Solution (50X) with 2,450 μL of Universal Assay Buffer (1X).

Prepare 1X Simplex Beads
Simplex kits are provided with concentrated 50X beads, which will require dilution before use. The dilution is dependent on the number of different Simplex Beads that are combined (Table 4).

IMPORTANT! ProcartaPlex™ Simplex Kits and/or Combinable Panels can be mixed for enhanced flexibility. Ensure that the bead regions from your ProcartaPlex™ Simplex Kits or panels do not overlap. Some analytes use the same bead region and cannot be combined in one multiplex assay. Check the compatibility of our analytes using our online panel configurator or contact our technical support.

1. Vortex each Simplex Bead vial (50X) for 30 seconds, then add 100 μL of each Simplex Bead vial (50X) to a mixing bottle if using a whole plate (otherwise adjust the volume accordingly).
2. Add Wash Buffer (1X) to a final volume of 5 mL. To combine 2 or more different Simplex Bead vials, follow Table 4 (using a whole plate):

Table 4   Dilution of Simplex Beads

Number of different Simplex Bead vials to be mixed| Total volume of mixed bead solution| Volume of Wash Buffer (1X) to add
---|---|---
1| 100 µL| 4,900 µL
2| 200 µL| 4,800 µL
3| 300 µL| 4,700 µL
4| 400 µL| 4,600 µL
5| 500 µL| 4,500 µL
6| 600 µL| 4,400 µL

Prepare 1X Detection Antibody Mixture
For simplex and combinable panels, detection antibody is provided at 50X concentration. Add 60 μL of each detection antibody concentrate to the mixing bottle and bring volume to a total of 3 mL using detection antibody diluent if using a whole plate (otherwise adjust the volume accordingly).

Number of vials of detection antibody| Total volume of detection antibody| Volume of diluent to add
---|---|---
1| 60 µL| 2,940 µL
2| 120 µL| 2,880 µL
3| 180 µL| 2,820 µL
4| 240 µL| 2,760 µL

Number of vials of detection antibody| Total volume of detection antibody| Volume of diluent to add
5| 300 µL| 2,700 µL
6| 360 µL| 2,640 µL

Prepare Standard Mix
Carefully review the Certificate of Analysis for lot-specific information on the kit components. The majority of kits are supplied with lyophilized Standard Mixes that contain a mix of multiple standard proteins. Some kits contain multiple sets of standards, each with a unique lot number, that require pooling prior to use. Each kit is shipped with two identical vials of each premixed antigen standard set from the same lot to permit the user to run the assay twice if running a partial plate. When combining multiple kits, ensure that the antigen standards of your analytes of interest are only present in one of the used standard vials. For instructions for combining more than five antigen standard sets, visit thermofisher.com/support.
When preparing antigen standards, the final volume after reconstitution and pooling should be 250 μL. For experiments measuring serum, plasma, urine, or CSF samples, use 1X UAB to reconstitute and dilute the standard. For experiments measuring cell culture supernatant samples, use fresh cell culture medium as the diluent.

Note: Change pipette tips after each dilution step and avoid air bubbles.

1. Centrifuge each different standard mix stock vial at 2,000 x g for 10 seconds.
2. Add 50 μL of diluent to each stock vial.
3. Vortex the vials at high speed for 30 seconds and centrifuge at 2,000 x g for 10 seconds to collect contents at the bottom of the vial.
4. Incubate on ice for 10 minutes to ensure complete reconstitution.
5. Pool entire content of each stock vial into one of the vials and fill up to a total volume of 250 μL.
6. Vortex the vial at high speed for 10 seconds and centrifuge at 2,000 x g for 10 seconds to collect contents at the bottom of the vials.

of standard sets| Reconstitution volume per vial| Pooled volume| Buffer to

add| Total volume
---|---|---|---|---
1| 50 μL| 50 μL| 200 μL| 250 μL
2| 50 μL| 100 μL| 150 μL| 250 μL
3| 50 μL| 150 μL| 100 μL| 250 μL
4| 50 μL| 200 μL| 50 μL| 250 μL
5| 50 μL| 250 μL| 0 μL| 250 μL

Prepare 4-fold serial dilution

1. Label the tubes in the 8-Tube Strip: Std1, Std2, Std3, Std4, Std5, Std6, and Std7.
2. Add 200 μL of the reconstituted standard mix into Std1 tube.
3. Add 150 μL of diluent into Std2–Std7 tubes.
4. Transfer 50 μL from Std1 tube into Std2 tube.
5. Mix by pipetting up and down 10 times.
6. Transfer 50 μL of the mixed standards from Std2 tube into Std3 tube using new pipette tip.
7. Mix by pipetting up and down 10 times.
8. Repeat steps 4–7 for tubes Std4–Std7, changing pipette tips between dilution steps, see Figure 1.
9. Add 150 μL of diluent to the last tube of the 8-Tube Strip to serve as a background.

Note: To assure a good bead count, the probe height must be adjusted to the plate provided in the kit. We recommend using two 5.08 mm spacer disks to adjust the sample probe height for Mylar-bottom plates.

Analyze results
The concentration of the samples can be calculated by plotting the expected concentration of the standards against the NET MFI generated by each standard. For Bio-Plex™ Manager, plot standard concentrations against FI-Bkgd. A 4PL or 5PL algorithm is recommended for the best curve fit. Analyze the assayed samples according to the operation manual for the Luminex™ or Bio-Plex™ instrument.
We offer a free and robust analysis software package for data analysis. To analyze the data, follow the instructions below or contact our technical support.

1. Export the run data in .csv format and navigate to the ProcartaPlex™ Analysis App on Thermo Fisher Connect: https://apps.thermofisher.com/apps/procartaplex
   Note : Before exporting .csv raw data from Bio-Plex™ Manager, please make sure to set ‘Analytes Labels’ under ‘Document Export Properties’ to ‘Name (Region)’. The .csv raw data exported as Report Type ‘xPONENT’ from INTELLIFLEXTM instruments are supported.

2. Upload the .csv files to the ProcartaPlex™ Analysis App to analyze the run data. The intuitive software features 4PL/5PL curve fit optimization, group-wise statistical and heat map analysis. Users can export detailed reports including images for presentations and publications.

Note: The sample dilution factor must be accounted for in the software analysis.
