Frequently Asked Questions (FAQ)
Q: Where can I store the Master Mix and Primer/Probe
Mixture?
A: Store both at -20°C to maintain stability and minimize
contamination risk.
Q: What is the purpose of the Negative extraction control
(NEC)?
A: NEC serves as a contamination control method for DNA
isolation by using RNase/DNase free water instead of algae.
Q: Why is the Positive control template (PCT) important?
A: PCT contains synthetic Anatoxin DNA for validation and should
show amplification in the FAM channel to ensure PCR run
validity.

Anatoxin qPCR detection Kit
Real-time quantitative analysis of the Anatoxin gene region AnaC
Catalog Number: NA2025
For Research Use Only. Not for use in Diagnostic Procedures.
1. Background Anatoxin is a class of hepatotoxin produced by blue-green algae
such as Anabaena flos-aquae. Cyanobacteria can produce Anatoxin in large
quantities during an algal bloom, which then poses a major threat to our
aquatic ecosystems and sources of food, as there is a well-documented
phenomenon called “bioaccumulation” that describes the increase in consumed
toxin quantities as trophic levels increase.
2. Test Principle Attogene’s PCR kit for Anatoxin is designed for the In
vitro analysis of the AnaC gene region responsible for assembling part of the
Anatoxin peptide. The AnaC gene region specific primer and probe mix is
provided to be detected through the FAM channel on a qPCR machine. A sample of
algae is obtained and washed to extract a clean algal gDNA sample. A reaction
mixture is assembled from primers, probe, master mix, and gDNA samples as
required. The qPCR machine of choice is set up and loaded as needed and the
mixture undergoes PCR amplification. The Primer mix provided exploits the Taq
polymerase to amplify the gene region of interest; while the DNA probe mixture
is cleaved during amplification to release its FAM fluorophore. The resulting
FAM release can be detected on a variety of qPCR platforms.
3. Applications This kit can be used for specific analysis of the Anatoxin C
gene region in liquid gDNA samples such as water, wastewater, and algal
cultures.

mixture (150 reactions) · 170ul AnaC region specific fluorescent probe (150
reactions) · 50ul AnaC region positive control template 1E8 copies/ul

6. Reagents Preparation Master Mix (not Provided)
-Caution this reagent is sensitive to contamination and should only be handled in a clean area away from positive control template. -Store at -20C. Master Mix is stable when stored at -20C. Freeze and thaw cycles should be minimized to increase shelf life. -If required aliquots of Master Mix should be made and stored at -20C to minimize freeze thaw and contamination risk.
Primer/ Probe Mixture -Caution these reagents are sensitive to contamination
and should only be handled in a clean area away from positive control
template. -Store at -20C. Primer/Probe is stable when stored at -20C. Freeze
and thaw cycles should be minimized to increase shelf life. -If required
aliquots of Primer/Probe should be made and stored at -20C in the dark to
minimize freeze thaw and contamination risk.
7. Control Preparation Negative extraction control (NEC)
-If necessary, prepare one NEC each time extracting DNA from your sample. -RNase/DNase free water is used in place of algae in the extraction system to create a negative for the DNA isolation method. – The NEC will serve as a contamination control method for the isolation.
No Template control (NTC) -If necessary, a NTC can made by replacing gDNA in
the PCR reaction with RNase/DNase free water -The NTC is used to check for
contamination during PCR plate set up
Positive control template (PCT) -The AnaC Positive control template contains a
high number of copy templates and should be handled away from specimen samples
and kit components. -The PCT contains synthetic Anatoxin DNA representing the
AnaC genomic region of interest. -To ensure PCR run validity, the PCT should
see amplification in the FAM channel. -Store at -20C. PCT is stable when
stored at -20C. Freeze and thaw cycles should be minimized to increase the
shelf life.
8. Assay Set Up
-gDNA isolation will need to be done before starting an experiment. For optimal results use >10ng/uL of gDNA with a ratio of >1.80 in your experiment. IEC multiplexing can also be done to ensure proper DNA extraction.
-Plate set up will vary with the quantity of samples you need to run on your plate. A NEC is preferably included in each plate set up. NTCs should be included in each plate
set up. A PCT must be included in each plate set up. The PCT should be added after all other reagents and samples have been added to the plate.
-Determine the number of reactions to set up in your assay (including NEC, PCT and any NTCs for your plate). It is necessary to make extra reaction mixture to allow for pipetting error.
-For convenience a large solution of PCR components will be mixed shortly before starting a reaction and subsequently aliquoted into your plate or tubes. Each PCR run will use 19uL of this reaction mixture and 1ul of isolated gDNA/NTC/PCT/NEC based on the experiment set up.
9. qPCR detection protocol
1. For each DNA sample prepare a reaction mix according to the table below:
(Include sufficient reactions for positive and negative controls)
Reagent

Quantity
10uL 7uL 1uL 1uL 19uL
2. Pipette 19uL of this mixture into each well according to your qPCR experimental plate set up.
3. Prepare your DNA templates for each reaction
4. Pipette 1uL of sample gDNA into each well, according to your experiment. For negative controls replace the gDNA sample with 1uL of RNase/DNase free water to bring the total volume to 20uL.
5. To prepare a standard curve dilution series.
- Pipette 90uL of RNase/DNase free water into 8 separate tubes and label 2) Pipette 10uL of Positive Control Template (1E8 copies/uL) into tube 1 3) Vortex thoroughly 4) Pipette 10ul from prior dilution into the next tube 5) Vortex thoroughly 6) Repeat steps 4-5 six more times

11. Expected Performance Before Interpreting results, it is necessary to
verify the integrity of the reaction. If the following criteria are not
satisfied, then testing needs to be repeated.
a. NEC is free from amplification in the FAM (465-510) channel.
b. NTC is free from amplification in the FAM (465-510) channel. c. PCT
produces amplification in the FAM (465-510) channel between CT 5-30 Manually
inspect amplification criteria are fulfilled for all samples to verify the
integrity of the results.
12. Interpreting the test results
If all the data analysis criteria are fulfilled, then each sample can be
assessed with the following metric:
Target Positive control Negative control
Result
–
Positive Quantitative result (calculate quantity)
–
–
Negative result
+/-
CT<35
Experiment failed (contamination)
+/-

–
+/-
Experiment failed
*The sample must be reinterpreted based on relative signal of the Target vs. Negative control.
