Hot Start Core Kit - red contains all reagents required for PCR (except template and primer) in one box combining simple handling with high flexibility. The remium quality polymerase, ultrapure dNTPs and the optimized complete reaction buffer ensure superior amplification results. The additional reaction buffer without MgCl2 in combination with the MgCl2 stock solution allows an easy optimization of difficult amplifications. The kit contains Hot Start Pol - red for easier handling and to facilitate the preparation of the master mix.
The kit provides improved specificity and sensitivity when amplifying low-copy-number targets in complex backgrounds or when prolonged room-temperature set up is required. 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 nonspecifically annealed primers and primer-dimer formation at low temperatures during PCR setup.
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.
Hot Start Pol - red requires no prolonged heating or denaturing step. The polymerase inhibiting aptamer is quickly released at the increased temperature of thermal cycling.
