This kit is applicable for fresh blood, blood stored at 4°C, frozen blood, and dried blood stains stored on Whatman903 or FTA commercial cards, and is compatible with all conventional anticoagulants (EDTA, Citrate Acid, Heparin, etc.). It contains Phanta Blood Super-Fidelity DNA Polymerase, which is modified based on Phanta Super-Fidelity DNA Polymerase. This enzyme has superior resistance to PCR inhibitors in whole blood samples and can amplify whole blood concentrations up to 40%. Equipped with optimized 2 × Phanta Blood Buffer V2, Blood Direct PCR Kit V2 can efficiently amplify genomic fragments up to 10 kb from whole blood samples.
