TaqMan Mutation Detection Assays

TaqMan™ Mutation Detection Assays are powered by competitive allele-specific TaqMan™ PCR (castPCR™ Technology) to detect and measure somatic mutations in genes associated with cancer research. The castPCR technology is highly specific and sensitive, and can detect rare amounts of mutated DNA in a sample that contains large amounts of normal, wild-type DNA. These assays are compatible with different sample types, such as cell lines, formalin-fixed paraffin-embedded (FFPE) tissue samples, and fresh frozen tissue samples.

castPCR technology

Competitive, allele-specific TaqMan PCR utilizes an allele-specific primer for mutant allele detection that competes with an MGB blocker oligonucleotide to suppress the wild-type background.

Somatic mutation detection

By combining the power of TaqMan and castPCR technologies, TaqMan Mutation Detection Assays give you:

  • Higher specificity—designed to block the wild-type and amplify only the mutant
  • Higher sensitivity—designed to detect somatic mutations down to 1 cancer cell in 1,000 normal cells
  • Faster workflow—3 hours from sample to result

With 819 assays for 47 known cancer research genes available today like KRAS, BRAF, KIT, JAK2, the TaqMan Mutation Detection Assays provide an innovative tool for your cancer research.

The TaqMan™ Mutation Detection IPC Reagent Kit is a set of optional internal positive control reagents that can be duplexed with any TaqMan Mutation Detection Assay to provide a positive PCR control result. The TaqMan Mutation Detection IPC Reagent Kit is pre-optimized for use with the TaqMan Mutation Detection Assays.

Order your TaqMan Mutation Detection Assays pre-plated into Fast or standard 96- or 384-well plates with the TaqMan™ Custom Plating Service. Save time and reduce the resources needed for large-scale experiments.

For data analysis, Applied Biosystems™ Mutation Detector™ Software allows users to determine the mutation status of their samples from TaqMan Mutation Detection Assay data collected on Applied Biosystems™ Real-Time PCR Systems.

Discrimination castPCR technology combines allele-specific TaqMan qPCR with allele-specific MGB oligonucleotide blocker to effectively suppress non-specific amplification from the off-target allele.
