T4 DNA Ligase is a ligation enzyme that can be used to join DNA fragments by catalyzing the formation of phosphodiester bonds between juxtaposed 5phosphate and 3
hydroxyl termini in double-stranded DNA using ATP as a coenzyme. Both blunt and cohesive end DNA ligation, as well as single-stranded nick repair of DNA, RNA and DNA/RNA, are possible using the T4 DNA ligase.
More Information
Applications
- Blunt and cohesive end DNA ligation
- Blunt end linker addition
- Single-strand DNA, RNA and DNA/RNA repair
- DNA fragment insertion into vectors
Source
Recombinant E. coli
Storage
–20°C
Unit definition
One ligation unit is defined as the amount of enzyme that ligates >90% of 6 µg of _Hin_d III-restricted lambda DNA in a 20 µl reaction volume in 30 minutes at 16°C. One unit of the enzyme corresponds to 0.008 Weiss units by the ATP-PPi exchange reaction in 66 mM Tris-HCl (pH 7.6), 6.6 mM MgCl2, 10 mM DTT, 66 µM ATP and 3.3 µM [32P]Na4P2O7.
Concentration
350 U/µl (2.8 Weiss units/µl)
