Hot Start Taq Polymerase

Hot Start PCR technique reduces non-specific amplifications and offers a convenient reaction set-up at room temperature. The enzymatic activity of hot start polymerase is blocked by an aptamer or antibody at ambient temperature and switched on automatically during the increased temperature of the initial annealing step. The polymerase is recommended for routine PCR applications, high throughput PCR or genotyping and provides an improved specificity and sensitivity when amplifying low-copy-number targets or working with complex backgrounds.
