Hot Diamond Taq®

Diamond Taq® polymerases

Hot 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.

Hot Diamond Taq® polymerase exhibits unique Hot Start characteristics and represents a completely new “Hot Start concept”. Hot start characteristics are not accomplished through chemically modification nor a blocking antibody but a proprietary agent prevents non-specific polymerization; thereby preventing primer-dimer formation and increasing the PCR yield of specific products. The enzyme needs very short activation time (100 % activated during the first PCR cycle) but is compatible with all existing protocols (from 20 sec. to 15 min. at 95 °C).

Hot Diamond Taq® polymerase is particularly recommended for PCR applications that require ultra low levels of bacterial & fungal DNA in Diagnostic and demanding Research fields but also for amplification of long and difficult templates.
