常见问题解答 (FAQ)
How can I reorder a Custom TaqMan Assay that I ordered previously?
To reorder the same Custom TaqMan Assay, you can follow these steps:
- Select an appropriate catalog number, considering the size of the assay that you want. You can find the different catalog numbers for Custom TaqMan Assays on their respective product pages on thermofisher.com.
- Once you have identified the necessary catalog number, go to www.thermofisher.com and click on "Quick Order", in the top right corner of the screen.
- In the following page, paste your selected catalog number in the "Catalog Number" field and paste the assay ID from your previous order in the "Assay ID" field.
- Click "Add to cart" and then in the following screen click "Proceed to check out".
Why do the values for the reference assay dye (VIC dye) vary for my TaqMan Copy Number Assay?
Please review the following possible causes and solutions:
-The reference sequence is not present or contains polymorphisms in the gDNA sample. Use an alternate copy number reference assay.
- There is variability in the amount of gDNA sample added to each reaction. Quantify the gDNA, then adjust the concentration of gDNA as needed.
Note: In general, the calculation of sample-level ΔCt accounts for variability in sample concentration.
- Pipetting was inaccurate. Check the pipette calibration of the pipettes, and pipette at least 5 µL of sample to prepare the reaction mix.
Why is the multicomponent signal for ROX dye not flat for my TaqMan Copy Number Assay?
Most likely incorrect dyes were selected for each target. Check the dyes selected for each target, then reanalyze the data.
Why was there a simultaneous increase in fluorescence from both the passive reference dye (ROX dye) and the reporter dyes for my TaqMan Copy Number Assay?
Most likely the sample evaporated. We recommend that you check the seal of the adhesive film for leaks before running the plate on the real-time PCR instrument.
Why was there a decrease in ROX dye fluorescence (passive reference dye) in my TaqMan Copy Number Assay?
Please review the following possible causes and solutions:
- There was insufficient Master Mix added to the reaction. Please follow accurate pipetting practices.
- Reagents are degraded. Ensure that the kits and reagents have been stored according to the instructions on the packaging and that they have not expired.
