ACTaq™ Mastermix is complete “ready-to-go” 2X reaction mix which only requires consumer researcher to add water, template and primers. Taq DNA Polymerase originates from Thermus Aquaticus with molecular weight of 94KDa. For use in DNA fragment extension amplification reactions with DNA having dA overhang on 3’ ends; at extension amplification speed of 1200 bases per minute and optimized between 65-75ºC. Optimized for best performance when using dNTP concentration at 100-300mM, 1.5-3.0mM Mg2+ concentration, and pH at 8.1-9.2.
