2x Taq PCR Premix


Description: 2x Taq PCR Premix is an ready-to-use optimized solution containing Taq DNA polymerase, standard Taq reaction buffer, dNTPs, tracking dyes and stabilizers. It is ideally suited to routine PCR applications such as sub-cloning, colony screening and genotyping. It can amplify up to 4 kb from complex genomic DNA or up to 5 kb from lambda DNA. Blue dye migrates approximately at 4 kb, and yellow dye migrates approximately at 50 bp.

Source: Recombinant Taq DNA polymerase purified from an E. coli strain carrying Thermus aquaticus gene.Taq DNA polymerase is a thermostable DNA polymerase that possesses a 5´→ 3´ polymerase activity and a double-strand specific 5´→3´ exonuclease activity. TP01-01 contains 250 units of Taq DNA polymerase. TP01-02 contains 1000 units of Taq DNA polymerase.

  • High-Throughput PCR

Storage Condition: 2x TaqPCR Premix should be stored at -20oC. Limited (up to 10 times) freeze-thaw does not affect PCR performance. For daily use, it’s recommended to keep an aliquot at 4°C, which is stable up to 6 weeks.

These recommendations serve as a starting point. In order to maximize amplification, the reaction conditions may require optimization.
  1. Thaw 2xTaq PCR Premix at room temperature and mix well by inverting several times before use.
