LeGene PCR Mix Gold is a ready-to-use reaction cocktail for PCR amplification up to 8 kb. It’s a 2X concentrated formulation that contains all necessary components including DnaUs Taq DNA polymerase, 3’-5’ proofreading thermostable DNA polymerase, magnesium, dNTPs, and stabilizer except primers and template. It consists of a mixture of Taq and proofreading thermostable DNA polymerase and provides 6-fold higher fidelity than Taq alone. Reagents sufficient for 250 PCR amplification reactions of 50 µl reaction volume.
