As we approach the Christmas & New Year period, we’d like to notify you of our final date for receiving routine orders to facilitate delivery before the Christmas break as Friday 15th December 2023.
The MyBio Team would like to take this opportunity to thank you for your business and continued support. We look forward to meeting you again in 2024.
DNA Polymerase I Large (Klenow) Fragment is a DNA-dependent DNA polymerase that lacks the 5'-->3' exonuclease activity of intact E. coli DNA Polymerase I but retains its 5'-->3' polymerase, 3'-->5' exonuclease and strand displacement activities. The enzyme is a 68kDa C-terminal fragment of DNA Polymerase I. The 5'-->3' polymerase activity of Klenow Fragment can be used to fill in 5'-protruding ends with unlabeled or labeled dNTPs, to sequence single- or double-stranded DNA templates, for in vitro mutagenesis using synthetic oligonucleotides, for cDNA second-strand synthesis and to generate single-stranded DNA probes. The 3'-->5' exonuclease activity can be used to generate blunt ends from a 3'-overhang.
