Advantages & Features
- Recombinant: isolated from E. coli cells with a cloned fragment of the polA gene.
- DNase I-dependent nick translation: second-strand synthesis in cDNA cloning, fill-in of 5´ overhangs.
- Generates probes using random primers.
- Creates blunt ends.
- Complete solution: supplied with 10x Reaction Buffer.
- Risk-free: product covered by our Quality 100% Guarantee.
One unit of the enzyme catalyses the incorporation of 10 nmol of deoxyribonucleotides into a polynucleotide fraction in 30 min at 37 °C, using poly(dA-dT)·poly(dAdT) as a template primer.
Includes for 500 U:
– 50 μL Klenow Fragment (10 U/μL)
– 1 mL Reaction Buffer (10x)
- DNA sequencing, fill-in of 5’ overhangs and removal of 3’ overhangs to form blunt ends and second strand synthesis in mutagenesis.
- DNA blunting by fill-in of 5’-overhangs or removal of 3‘-overhangs.
- Random-primed DNA labeling.
- Labeling by fill-in 5’-overhangs of dsDNA.
- DNA sequencing by the Sanger method.
- Site-specific mutagenesis of DNA with synthetic oligonucleotides.
