Taq DNA polymerase (1000 units) is molecular grade enzyme for molecular biology experiments such as DNA amplification with 3 U/l. Taq stands for Thermus Aquaticus a organisms from which the enzyme has been isolated. Some polymerase enzyme didnt show proper amplification as they can not bind properly. Taq polymerase is a thermostable enzyme which stay active even at high temperatures such as 92 degree celsius. Taq DNA Polymerase can be supplied with10X buffer containing 15 mM MgCl or 10X buffer. It should be stored at -20-degree Celsius for long term use and activity of an enzyme. Avoid frequent freeze and thaw to maintain the stability of polymerase.
