•高温灭活:DNA Polymerase I Large (Klenow) Fragment,Exonuclease Minus 在75℃加热10 分钟失活。
原厂资料:
DNA Polymerase I Large (Klenow) Fragment, Exonuclease Minus, is a DNA-dependent DNA polymerase that lacks both the 5´→3´ and the 3´→5´ exonuclease activities present in intactE. coliDNA Polymerase I. It is used for random primer labeling and in strand displacement amplification. Klenow Fragment, Exonuclease Minus, will leave a single-base 3´ overhang on a significant proportion of DNA fragments during fill-in of 5´-overhangs. Therefore, this enzyme is not recommended for preparation of blunt-ended fragments for ligation.
