Thermo Scientific™ Klenow Fragment, exo– (5 U/μL)

Klenow Fragment, exo- is the large fragment of DNA polymerase I. Exhibits 5'→3' polymerase activity, but lacks the 3'→5' and 5'→3' exonuclease activities.

Supplier:  Thermo Scientific™ EP0422

Catalog No. FEREP0422

Description

Klenow Fragment, exo-, is the large fragment of DNA polymerase I . It exhibits 5'→3' polymerase activity, but lacks the 3'→5' and 5'→3' exonuclease activities of DNA Polymerase I. The 3'→5' exonuclease activity of the enzyme is eliminated by mutations in the 3'→5'-exonuclease active sit.

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

Specifications
