T4 DNA Ligase catalyzes the formation of
phosphodiester bonds between 3′-hydroxyl
and 5′-phosphate groups of adjacent DNA and
RNA nucleotides in blunt-end or cohesive-end
configurations. The enzyme joins RNA
and DNA strands only in duplex molecules
and does not join single-stranded nucleic
acids. Novagen T4 DNA Ligase is rigorously
tested in a blue-white cloning assay under
conditions that maximize exposure of DNA
ends to any contaminating nucleases. The
enzyme is qualified for any ligation or cloning
application.
