Invitrogen AccuPrime DNA polymerases utilize AccuPrime accessory proteins for improved PCR fidelity, yield, and specificity. AccuPrime™ technology is available in Taq, Pfx, GC-Rich, and SuperMix formulations.
AccuPrime DNA Polymerases
Overview of AccuPrime Technology
The thermostable AccuPrime accessory proteins enhance specific primer–template hybridization during every cycle of PCR, preventing mispriming and improving PCR specificity and yield. In addition, AccuPrime enzymes are designed with Platinum antibodies that are specific to the DNA polymerase and inhibit its activity at room temperature, providing an automatic hot start.
