T4 DNA Ligase

About

T4 DNA ligase is an enzyme that facilitates the joining of DNA stands by catalyzing phosphodiester bonds. It was isolated from [http://en.wikipedia.org/wiki/Enterobacteria_phage_T4 bacteriophage T4] and is used to generate recombinant DNA sequences.[1]

Working conditions

For ligating extended oligos in a PCR reaction it is necessary to have phosphorilated 5'-ends. Oligos will only be ligated when they are assembled on a compementary strand. [2]
