Conventional PCR
Non-specific extension of primers at low temperature is a common cause of PCR artifacts and poor assay specificity and sensitivity.
Quantabio PCR reagents are formulated with ultrapure AccuStart DNA polymerase, which contains a stringent antibody hotstart to ensure specific and efficient primer extension only after activation at 94°C. Our enzymes are rigorously purified to remove host E. coli genomic DNA and are ideally suited for applied testing applications such as bacterial pathogen detection where residual host DNA in typical recombinant enzyme preparations can limit assay sensitivity and obscure detection of low copy targets.
Available in a variety of optimized formulations designed to support specific PCR applications and starting materials.
