DIFFERENT RESULTS BY DIFFERENT COMMERCIAL TAQ DNA POLYMERASE IN RAPD

摘要

@@ RAPD (Random Amplified Polymorphic DNA) technique has been widely used in animal, plant, human and microorganism research since it was first established by Williams in 1990[1-3]. But, because of low annealed temperature and short 10-nt primers, the resolution and repetition is low in RAPD. The stability of RAPD is influenced by many factors such as the concentration of template, primers, dNTP, Mg++,and Taq DNA polymerase[4-6]. The influence on amplified products of different commercial Taq DNA polymerase in RAPD was studied in this paper.
