T4 DNA Ligase catalyzes the joining of two strands of DNA between the 5´-phosphate and the 3´-hydroxyl groups of adjacent nucleotides in either a cohesive-ended or blunt-ended configuration. The enzyme has also been shown to catalyze the joining of RNA to either a DNA or RNA strand in a duplex molecule but will not join single-stranded nucleic acids.
The T4 DNA Ligase Buffer Pack includes 3 tubes of T4 DNA Ligase 10X Reaction Buffer. The composition of the 10X reaction buffer is 300mM Tris-HCl (pH 7.8 at 25°C), 100mM MgCl2, 100mM DTT and 10mM ATP.
