Applied Biosystems™ TaqMan™ 5'-nuclease assay chemistry provides a fast and simple way to get single nucleotide polymorphism (SNP) genotyping results. Each predesigned Applied Biosystems™ TaqMan™ SNP Genotyping Assay in our massive collection includes two allele-specific Applied Biosystems™ 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 Applied Biosystems™ OpenArray™ real-time PCR instrument formats, you can select the workflow that best fits your genotyping needs.

1.7 million new TaqMan SNP Genotyping Assays
These assays enhance our coverage of SNPs discovered by large sequencing projects such as the international HapMap project and 100 genomes project. The newly updated SNP assay collection now features > 6.2 million pre-designed SNP assays.
