When, where, and under what conditions are genes expressed? What triggers, or prevents, this expression? Scientists are discovering the surprisingly wide range of products of transcription and translation, and how these different expression products determine the growth and health of an organism.
With carefully selected content, TaqMan gene expression assays and arrays can generate high-quality data for a broad range of studies, providing over 2.3 million pre-designed primer/probe sets covering more than 30 species.
Our new Vietnam channel partners specializing in genetic analytic products are here to support you.
Common gene expression research applications:
Real-time PCR
- Cancer research
- Immuno-Oncology
- Neurodegenerative and complex disease
- Validate results from other technologies (NGS, Microarray)
- Pathway analysis
- Biomarker signatures
- eQTL analysis
- Mid- to high-throughput studies using the OpenArray platform
We have developed two chemistries for the sensitive, accurate quantification of mRNA using real-time PCR: Applied Biosystems TaqMan probe–based chemistry, and Applied Biosystems SYBR Green dye–based chemistry.

Alternatives and options when performing gene expression using real-time PCR (qPCR) or digital PCR
- TaqMan Gene Expression Assay formats
Available formats in pre-configured, configurable, or custom options based on your research needs, throughput, and number of targets. - Digital PCR (dPCR)
Rare target detection and Absolute quantification of nucleic acid standards & next-generation sequencing libraries - TaqMan PreAmp Master Mix
Amplify your cDNA before using it for the real-time PCR reaction. It will increase the amount of cDNA available for subsequent reactions without creating bias in the relative amount of cDNA represented in your sample. This method can be used to help enable single-cell studies. - One-step RT-PCR reagents
By combining reverse transcription (RT) and real-time PCR amplification (qPCR) reagents into a single reaction, you are able to reduce the number of hands-on manipulations required as well as the total time to process your samples and get data. It is ideal for situations where many samples are being screened for a few targets, or when automating your experiments with liquid handling systems. One potential drawback is that all of the cDNA is used in the qPCR, so none is left over for later use. - Cells-to-CT kits and other integrated sample preparation/real-time PCR products
These products eliminate the need for nucleic acid purification, creating much simpler experimental protocols and reducing the effort for sample preparation to just a few minutes.
