Description and Specification

Specification

Concentration 5U/┬ÁL
Inhibitors metal chelators, PPi, Pi (at high concentrations) (7)
Source E.coli cells with a cloned DNA fragment of the mutated polA gene
Molecular Weight 68kDa monomer
Units 300U

Highlights

  • Lacks 3'→5' exonuclease activity
  • Incorporates modified nucleotides (e.g., Cy3-, Cy5-, fluorescein-, rhodamine-, aminoallyl-, biotin-labeled nucleotides)
  • Active in restriction enzyme, PCR, and RT buffers

Applications

  • Random-primed DNA labeling
  • Labeling by fill-in 5'-overhangs of dsDNA
  • Strand displacement amplification (SDA)
  • DNA sequencing by the Sanger method

Note

Klenow Fragment, exo- is not recommended for DNA blunting reactions prior to DNA ligation since it frequently adds one or more extra nucleotides to the 3'-terminus of blunt-end DNA substrates in a non-template directed fashion
