TaqMan® SNAP Assays

Applied Biosystems TaqMan 5'-nuclease assay chemistry provides a fast and simple way to get single nucleotide polymorphism (SNP) genotyping results. Each predesigned TaqMan SNP Genotyping Assay in our massive collection includes two allele-specific TaqMan MGB probes containing distinct fluorescent dyes and a PCR primer pair to detect specific SNP targets. These TaqMan probe and primer sets (assays) uniquely align with the genome to provide unmatched specificity for the allele of interest. With more than 6.2 million predesigned TaqMan SNP Genotyping Assays available for use with 48-, 96-, 384-well and OpenArray real-time PCR instrument formats, you can select the workflow that best fits your genotyping needs.
