Low DNA qPCR master mix contains a chemical hot-start Taq polymerase and highly optimized reaction buffer with dNTPs, MgCl2, stabilizers and PCR enhancers. The Taq polymerase is purified twice, before and after the addition of the chemical hot-start, this helps to remove trace amounts of DNA (known as bioburden) that come from the manufacturing of the DNA polymerase. In addition there is no bioburden that comes with antibody hot-start, making it ideal for low-copy number targets and also microbial DNA and fungal DNA detection assays. Low DNA qPCR master mix can also be used for fast, precise and highly reproducible genotyping of sequence variants, including loci, provides higher stringency and more specific binding of the allele-specific probes, with wider and clearer separation of allele cluster.
