Description Methylamp Hot Taq DNA Polymerase is a chemically modified Methylamp Taq DNA Polymerase. At ambient temperatures it is inactive, having no polymerization activity. Methylamp Hot Taq DNA Polymerase is activated by a 15 min incubation step at 95°C. This prevents extentension of non-specifically annealed primers and primer-dimers formed at low temperatures during PCR setup. The enzyme has 5’→3’ polymerization dependent exonuclease replacement activity but lacks 3’→ 5’ exonuclease activity.
Concentration5 units/µl (one unit is defined as the amount of enzyme required to catalyze the incorporation of 10 nmol of dNTP into an acid-insoluble form in 30 min at 74°C).
SourcePurified from an E. coli strain carrying an overproducing plasmid containing a modified gene of Thermus aquaticus DNA Polymerase.
Storage & Dilution Buffer50% glycerol (v/v), 20 mM Tris-HCl pH 8.7 at 25°C, 100 mM KCl, 0.1 mM EDTA and stabilizers.
