Description

The Maxwell ® RSC Blood DNA Kit (a) is used with the Maxwell ® RSC or Maxwell ® RSC 48 Instruments to provide an easy method for efficient, automated purification of genomic DNA (gDNA) from samples. The Maxwell ® RSC and Maxwell ® RSC 48 Instruments are supplied with preprogrammed purification procedures and are designed for use with predispensed reagent cartridges, maximizing simplicity and convenience. The Maxwell ® RSC Instrument can process up to 16 samples and the Maxwell ® RSC 48 instrument can process up to 48 samples. Both instruments can process the maximum number of samples in about 40 minutes. The purified DNA can be used directly in a variety of downstream applications.
The Maxwell ® RSC Blood DNA Kit purifies samples using a novel paramagnetic particle, called the MagnaCel™ particle, which provides a mobile solid phase that optimizes sample capture, washing and purification of gDNA. This particle utilizes cellulose-based binding of nucleic acids and provides a higher bind capacity and cleaner eluate than traditional DNA purification. The Maxwell ® RSC and Maxwell ® RSC 48 are magnetic particle-handling instruments that efficiently bind gDNA to the paramagnetic particle in the first well of a prefilled cartridge. The samples are processed through a series of washes before the gDNA is eluted.

Description (continued)
Prior to extraction, samples can be preprocessed manually or using the Maxprep™ Liquid Handler. The Maxprep™ Liquid Handler will scan bar codes and transfer samples from primary blood tubes, perform sample lysis prior to extraction, transfer lysed samples to Maxwell ® RSC Blood DNA cartridges, add plungers to Maxwell® RSC Blood DNA cartridges, and add Elution Buffer to elution tubes. Instructions are provided for preprocessing samples manually or with the Maxprep™ Liquid Handler.

   a. The specified volume of whole blood
   b. 30µl of Proteinase K Solution
   c. 300µl of Lysis Buffer

2. The Processing Plate incubates for 20 minutes.

3. During the lysis incubation, plungers are transferred to each of the cartridges in the Maxwell ® RSC or Maxwell ® RSC 48 deck trays. The specified volume of Elution Buffer is transferred to the elution tubes for each position in the Maxwell ® RSC or Maxwell ® RSC 48 deck tray.

4. After lysis incubation is complete, each sample is transferred from the Processing Plate to its corresponding Maxwell ® RSC cartridge.

5. Once the method is complete, open the Maxprep™ Liqiud Handler door, and transfer the deck trays to your Maxwell ® RSC or Maxwell ® RSC 48 Instrument for extraction. Remove primary sample tubes and Processing Plate, and discard the used tips from the waste bin as hazardous waste following your institution’s recommended guidelines. Either discard or tightly cap and store remaining reagents.

Consumables used by the Maxprep™ Instrument for preprocessing methods are designed to be used with potentially infectious substances. Use appropriate protective equipment (e.g., gloves and goggles) when handling infectious substances. Adhere to your institutional guidelines for the handling and disposal of all infectious substances when used with this system.

   Warning: Pinch point hazard.
   The Maxwell ® Instrument will immediately begin the purification run. The screen will display information including the user who started the run, the current method step being performed, and the approximate time remaining in the run.
   Notes:
   1. When using the Maxwell ®  RSC 48 Instrument, if the Vision System has been enabled, the deck trays will be scanned as the door retracts. Any errors in deck tray setup (e.g., plungers not in well #8, elution tubes not present and open) will cause the software to return to the ‘Cartridge Setup’ screen and problem positions will be marked with an exclamation point in a red circle. Resolve all error states, and press the Start button again to repeat deck tray scanning and begin the extraction run.
   2. Pressing the Abort button will abandon the run. All samples from an aborted run will be lost.
   3. If the run is abandoned before completion, you may be prompted to check whether plungers are still loaded on the plunger bar. If plungers are present on the plunger bar, you should perform Clean Up when requested. If plungers are not present on the plunger bar, you can choose to skip Clean Up when requested. The samples will be lost.

8. Follow on-screen instructions at the end of the method to open the door. Verify that plungers are located in well #8 of the cartridge at the end of the run. If plungers are not removed from the plunger bar, follow the instructions in the Maxwell ® RSC Instrument Operating Manual or the Maxwell ® RSC 48 Instrument Operating Manual to perform a Clean Up process to attempt to unload the plungers.

9. Remove the deck tray(s) from the instrument. Remove elution tubes containing DNA, and cap the tubes. After the run has been completed, the extraction run report will be displayed. From the “Report View’ screen, you can print or export this report or both.

10. Remove the cartridges and plungers from the deck tray, and discard as hazardous waste following your institution’s recommended guidelines. Do not reuse reagent cartridges, plungers or elution tubes.
    Ensure samples are removed before performing any required UV light treatment to avoid damage to the nucleic acid. 6422MA

multiple freeze-thaw cycles may have degraded DNA. Use fresh samples whenever possible, or avoid multiple freeze-thaw cycles.
Proteinase K Solution was not added. The lysis and yield are dependent upon complete extraction with Proteinase K. If Proteinase K was not added in Section 3.A, Step 3, or set up on the MaxprepTh Liquid Handler, the resulting blood sample will be red. Proteinase K-treated samples turn greenish brown. This can be used as a quick diagnostic method of determining whether or not Proteinase K was added.
Whole blood sample contained low white blood cell count. The yield of genomic DNA from blood samples depends on the number of white blood cells present in the sample
Whole blood sample was not mixed before processing. Be sure to mix whole blood samples before processing to ensure that the white blood cells are in suspension.
The Maxwell® RSC or RSC 48 Instrument was set for the wrong method. Ensure that the Blood DNA method is chosen.
RNA contamination in DNA eluates| In some cases, total RNA can be copurified with the genomic DNA. To remove copurified RNA, an RNase treatment can be performed. Add 5111 of RNase A (Cat.* A7973) per milliliter of Elution Buffer.
Instrument unable to pick up plungers| Make sure you are using an RSC-specific chemistry kit; the plungers for the Maxwell® RSC reagent kits are specific for the Maxwell® RSC or RSC 48 Instruments.
