  • High yield, high sensitivity PCR
  • Premixed PCR master mix for convenient amplification requiring minimal assembly 
  • Generation of PCR products having >80% cloning efficiency in T-vectors



TaKaRa Premix Ex Taq* 6 x 500 µL

*Contains TaKaRa Ex Taq, Ex Taq Buffer, 4 mM MgCl and dNTPs.


–20°C. Avoid repeated freeze-thaw and vigorous stirring of product. Once thawed, aliquot product into PCR tubes and store at –20°C.

PCR Performance

Enzyme performance is confirmed by successful amplification of a 20 kb lambda DNA template. PCR amplification of a single copy gene (Beta-globin) by PCR is confirmed using human genomic DNA as the template (amplified fragment: 17.5 kb).

PCR Products

PCR products generated with Ex Taq DNA Polymerase contain a mixture of 3'-A overhangs and blunt ends, resulting in >80% cloning efficiency in T-vectors.
