Versatile Dna Polymerase - Large Klenow Fragment Flash Sale: 35% Off [IWBc9dNH]

DNA Polymerase Large (Klenow) Fragment is a truncated fragment of E. coli DNA Polymerase I that lacks the 5´→ 3´ exonuclease activity but retains its 5´→ 3´ polymerase, 3´→ 5´ exonuclease (proofreading) and strand displacement activities. 

Applications:

• Random primer labeling of DNA
• Labeling by fill-in 5'-overhangs of dsDNA
• Conversion of 5´-overhangs to create blunt-ends for cloning
• Removal of 3´-overhangs
• Second-strand synthesis of cDNA
• Site-directed DNA mutagenesis using synthetic oligonucleotides
• Dideoxy DNA sequencing of single- or double-stranded DNA templates
• Strand displacement amplification
