DNA Polymerase I Large (Klenow) Fragment

商品詳情參考文獻(xiàn) 相關(guān)資料

	Print Version
Description	DNA Polymerase I Large (Klenow) Fragment is the large fragment of E. coli DNA Polymerase I (abm Cat. No. G469). The Klenow Fragment retains the DNA-dependent DNA polymerase activity of the E. coli DNA Polymerase I but lacks the 5’→3’ exonuclease activity. With its inherent 3’→5’ exonuclease activity, Klenow possesses the polymerization fidelity of the holoenzyme without degrading 5'-termini.
Application	DNA blunting by filling-in 5'-overhangs with unlabeled or labeled dNTPs cDNA second-strand synthesis Generate single-stranded DNA probes using random primers Site-directed DNA mutagenesis using synthetic oligonucleotides Dideoxy DNA sequencing of single- or double-stranded DNA templates 3’→5’ exonuclease activity can blunt a 3’-overhang
Form	Enzyme supplied with 10X Reaction Buffer
Image
Concentration	5 U/μl
Storage	Store all components at -20°C.
Storage Buffer	25 mM Tris-HCl (pH 7.5), 0.1 mM EDTA, 1 mM DTT, and 50% (v/v) Glycerol.
Notes	One unit is defined as the amount of DNA Polymerase I Large (Klenow) Fragment that catalyzes the incorporation of 10 nmol of dNTP into acid insoluble material in 30 minutes at 37°C using poly(dA-dT):poly(dA-dT) as a template:primer. This product is distributed for laboratory research only. Caution: Not for diagnostic use.
