Diamond Taq®

Diamond Taq® polymerases

Diamond Taq® polymerase* is a highly thermostable enzyme produced and purified from recombinant Escherichia coli bacterium containing the Thermus aquaticus DNA Polymerase gene. The expressed enzyme catalyzes 5’→3’ synthesis of DNA with no detectable 3’→5’ proof reading exonuclease activity. This enzyme has the “extendase” activity allowing TA cloning.

Diamond Taq® polymerase is particularly recommended for PCR applications that require ultra low levels of bacterial & fungal DNA in Diagnostic and demanding Research fields. Visual confirmation of pipetting (inert red dye) can be included in the storage buffer, see Red Diamond Taq®.

Diamond Taq® polymerase can be ordered according to your needs :
