Description

Includes

1000 units of DNA polymerase in a storage buffer of 50mM potassium phosphate (pH 7.0), 100mM KCl, 1mM DTT, and 50% (v/v) glycerol. It is supplied at 5-10 units/μL.

DNA polymerase with 5'→3' and 3'→5' exodeoxyribonuclease activities

Performance and quality testing
Endodeoxyribonuclease assay; efficiency of DNase I-dependent nick translation determined.

Unit definition
One unit incorporates 10nMol of total deoxyribonucleotide into acid-precipitable material in 30 min at 37°C using template/primer.

Unit reaction conditions
50mM potassium phosphate (pH 7.0), 6.7mM MgCl2 , 1mM 2-mercaptoethanol, 80μg/mL template/primer, 32μM dTTP, 69nM [3H]dTTP, and enzyme in 100μL for 30 min at 37°C. Also incorporates biotinylated nucleotides.

  • Applications: DNase I-dependent nick translation, second-strand synthesis in cDNA cloning, fill-in of 5' overhangs
  • Source: purified from E. coli expressing the DNA Polymerase I gene on a plasmid

Cloning, Restriction Enzyme Cloning
