150,000 U of T4 DNA Ligase (120,000 U/mL) and 10x T4 DNA Ligase Buffer
The T4 DNA Ligase is intended for molecular biology applications. This product is neither intended for the diagnosis, prevention or treatment of a disease, nor has it been validated for such use either alone or in combination with other products.
Features
- Versatile enzyme widely used for high-precision NGS library prep and DNA cloning
- Efficiently joins both complementary cohesive (sticky) ends and blunt ends
- Repairs single-stranded nicks in duplex DNA for high-efficiency DNA ligation
- High-concentration rapid formulation increases efficiency and decreases ligation times
- Quality tested for the absence of DNase contamination
T4 DNA Ligase enzyme is a recombinant protein (55,292 Daltons) produced by an E. coli strain carrying the cloned bacteriophage T4 DNA ligase gene.
T4 DNA Ligase is an ATP-dependent enzyme that catalyzes the formation of a phosphodiester bond between the terminal 5ʹ phosphate and a 3' hydroxyl group of duplex DNA or RNA. The enzyme efficiently joins blunt and cohesive ends and repairs single-stranded nicks in duplex DNA, RNA or DNA:RNA hybrids (1). T4 DNA Ligase is effective for joining blunt or cohesive ends in double-stranded RNA with a complementary "splint" strand (DNA or RNA) holding the RNA ends together. T4 DNA Ligase cannot join single-stranded nucleic acids.
