Applied Biosystems Custom TaqMan Gene Expression assays, VIC primer-limited, are the custom version of our predesigned TaqMan assays for quantitative real-time PCR. Custom TaqMan Gene Expression assays consist of a pair of unlabeled PCR primers and a TaqMan probe with a dye label (VIC) on the 5’ end and a minor groove binder (MGB) and nonfluorescent quencher (NFQ) on the 3’ end.

Features include:
Easy to use—just add cDNA and master mix and run the qPCR—no melt curves required
Specific—TaqMan assays use proprietary MGB-containing probes that can be up to 15 bases shorter than non-MGB probes, improving the specificity of the assay
Sensitive—TaqMan assays are ideal for measuring low levels of expression or low-abundance targets
Accurate—identify small fold-changes with high accuracy of quantitation
Gold-standard TaqMan qPCR chemistry—TaqMan assays draw on Thermo Fisher Scientific's bioinformatics assay design pipeline to help ensure high specificity and minimal cross-reactivity, even for gene variants with high sequence homology
Ideal for multiplexing—combine one FAM-labeled and one VIC-labeled assay to create a duplex assay for two different gene targets in the same qPCR well
Ideal for control assays—use a VIC primer-limited assay for high-expressing endogenous control genes
Sequences provided—with every Custom TaqMan Gene Expression you design and order

Approximate ship time
Made to order: 4–6 days in North America, 6–10 days in Europe

Pre-formulated assay
• 2 unlabeled PCR primers (150 nM each final 1X concentration)
• 1 VIC dye-labeled TaqMan MGB probe (250 nM final 1X concentration)

TaqMan Gene Expression assays are the gold standard in real-time PCR gene expression studies, built on more than 20 years of experience. Each assay includes target primers and a sequence-specific probe optimized for the best functional performance. No additional design, optimization, or melt curve analysis is needed. Available in a wide variety of formats and species, new assay designs are constantly added to help meet your research needs. TaqMan assays have been cited in over 40,000 publications and are backed by more than 350 patents.

Frequently asked questions (FAQs)

Can I check the end product of a TaqMan Gene Expression Assay by running an agarose gel?

Yes, you can check the end product on an agarose gel. If you use the TaqMan Universal PCR Master Mix (including AmpErase UNG, Cat. No. 4304437), we recommend running the gel immediately after the PCR, since the trace amount of AmpErase UNG may digest the end product that contains double-stranded DNA with dUTP incorporated. The average length of amplicon ranges from 50-150 bp. The exact amplicon length is indicated on the detailed page of each assay on our website. You can get to that page by clicking on the Assay ID; the amplicon information is listed in the section "Assay Details".

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".

Can I perform a one-step RT-PCR reaction using TaqMan Gene Expression Assays?

While TaqMan Gene Expression Assays can be used to perform a one-step RT-PCR reaction, these assays have not been optimized for this application. TaqMan Gene Expression Assays have been designed, tested, and optimized using Applied Biosystems universal conditions for a two-step RT-PCR reaction.

When preparing the TaqMan or Custom TaqMan Gene Expression Assays, what is the recommended reaction volume?

When preparing the TaqMan or Custom TaqMan Gene Expression Assays, the recommended and supported volume is 20-50 µL for a 96-well standard plate set-up; 10-20 µL for a 96-well fast plate set-up and 5-10 µL for a 384-well set-up. For more information, please consult the TaqMan Gene Expression Assays and Custom TaqMan Gene Expression Assays protocols.

How much cDNA is recommended per TaqMan or Custom TaqMan Gene Expression reaction?

For optimal performance of the TaqMan and Custom TaqMan Gene Expression Assays, use 1 to 100 ng of cDNA per 50 µL total reaction volume. For more information, please consult the TaqMan Gene Expression Assay protocol and Custom TaqMan Gene Expression Assay protocol.
