SpeedTaq HOT DNA Polymerase
|
| |
The SpeedTaq HOT DNA Polymerase is specially optimized for rapidPCR but also provides improved specificity and sensitivity when amplifying low-copy-number targets in complex backgrounds or when prolonged room temperature set up is required. Due to a synthesizing speed of 200 bp/sec, extension times and in return the total reaction time is reduced to a minimum. The polymerase activity is blocked at ambient temperature and switched on automatically at the onset of the initial denaturation. The thermal activation prevents the extension of non-specifically annealed primers and primer-dimer formation at low temperatures during PCR setup. Thus it is optimal for amplifications running on rapidPCR thermal cyclers, as the SpeedCycler family from Analytik Jena | bio solutions. The enzyme catalyzes the polymerization of nucleotides into duplex DNA in 5‘ - 3‘ direction in the presence of magnesium. It also possesses a 5‘ - 3‘ polymerization-dependent exonuclease replacement activity but lacks a 3‘ - 5‘ exonuclease activity. SpeedTaq HOT DNA Polymerase requires no prolonged heating or denaturing step. The polymerase inhibiting ligand is quickly released at the increased temperature of thermal cycling.
