T4 RNA Ligase 1 catalyzes the ATP-dependent ligation of 5' phosphoryl-terminated nucleic acid donor to a 3' hydroxyl-terminated nucleic acid acceptor through the formation of a 3'→5' phosphodiester bond.
An ideal template is short single-stranded RNA (e.g. miRNA) that can be labeled at the 3'-OH group using labeled pCp as substrate. 3' End Labeling of longer RNA can be achieved with Poly(A) Polymerases.
Recommended final ATP concentration: 1 mM
