DNA Polymerase I (Pol I) catalyzes the incorporation of dNTPs into double-stranded DNA in a 5"→3" direction that is complementary to the DNA or RNAtemplate strand. It possesses 3"→5" exonuclease (proofreading) activity as well as 5"→3" exonuclease activity, making the enzyme useful for DNA end blunting and DNA labeling by nick translation. DNA Polymerase I is supplied in a buffer of 50 mM potassium phosphate (pH 6.5), 1 mM DTT and 50% glycerol.

我分别用3ul、5ul、8ul都试过了,没有任何条带,用别人别的方法提好的DNA做,却能出现结果,不知道是自己提取的DNA浓度不够,还是根本没有提取出来。
不知道谁用过,或者有更好的全血提取NDA的试剂盒推荐呢?
本人刚刚开始做PCR,谢谢各位高手!
