T4 DNA Ligase

Description
T4 DNA Ligase catalyzes the formation of a phosphodiester bond between juxtaposed 5'-phosphate and 3'-hydroxyl termini in duplex DNA or RNA. This enzyme will join blunt-end and cohesive end termini as well as repair single stranded nicks in duplex DNA, RNA, or DNA-RNA hybrids.

Concentrations
50 - 200u/μl

Features

  • Ultrapure recombinant protein
  • Seals single-stranded nicks in duplex DNA, RNA or DNA-RNA hybrids.
  • ATP is an essential cofactor for the reaction.

Supplied With
10X Buffer T4 Ligase

50mM Tris-HCl (pH7.8 at 25˚C), 10mM MgCl2, 10mM DTT, 1mM ATP and 25μg/ml BSA. Store at -20˚C.

Storage Buffer
10mM Tris-HCl (pH7.5), 50mM NaCl, 0.1mM EDTA, 10mM 2-mercaptoethanol and 50% glycerol. Store at -20˚C.

Thermal Inactivation
65˚C for 15 minutes

Unit Definition
1u (*Cohesive End Ligation Unit) is defined as the amount of enzyme that is required to give 50% ligation of Hind III fragments of lambda DNA (5' DNA termini concentration of 0.12μM [300μg/ml]) in 20μl of 1X T4 DNA Ligase Buffer in 30 minutes at 16˚C.

*One Cohesive End Ligation Unit is equal to 0.015 Weiss units. Equivalently, one Weiss unit is equal to 67 Cohesive End Ligation Units.

Application

  • Catalyzes the linkage of 5' or 3' blunt/cohesive ends of double-stranded DNA by formation of phosphodiester bond.
  • Joining of oligonucleotide linkers or adapters to blunt ends.
  • Repair nicks formation in duplex nucleic acids.

Quality Control
All preparations are assayed for contaminating endonuclease, exonuclease and non-specific DNase activities.
