T4 DNA Ligase

T4 DNA Ligase catalyzes the formation of phosphodiester bonds between 5' and 3' termini in double stranded DNA using ATP as a cofactor. The enzyme can be used for ligation of both blunt and sticky ends as well as single-stranded DNA nick repair. 

Edna T4 DNA Ligase products are recombinantly produced in E. coli and thus are free from contaminating nucleases, offering robust and reliable ligation activity.

What's In The Box:

The product includes one vial of recombinant enzyme at standard or high concentration, along with one vial of 10x ligation buffer.

1X Standard Ligation Buffer:

50 mM Tris-HCl
10 mM MgCl2
1 mM ATP
10 mM DTT
pH 7.5 @ 25°C

Highlights:

• Cloned from Bacteriophage T4 and recombinantly produced in E. coli with >99% purity

• Available at standard or high concentration for when minimal dilution is critical

• Detergent free formulations compatible with post-processing applications

• Ideal for cloning of restriction enzyme generated DNA fragments and PCR products
