T4 RNA Ligase 1 catalyzes the ligation of a 5´ phosphoryl-terminated nucleic acid donor to a 3´ hydroxyl-terminated nucleic acid acceptor through the formation of a 3´ → 5´ phosphodiester bond, with hydrolysis of ATP to AMP and PPi. Substrates include single-stranded RNA and DNA as well as dinucleoside pyrophosphates.

    Avoiding RNase Contamination
T4 RNA Ligase 1, High Concentration (M0437M), is a 3X higher concentration than our standard T4 RNA Ligase 1 (M0204S/L). This product is packaged with a vial of 100 mM ATP (N0451A). The increased concentration of reaction components is helpful in lower volume reactions where reagent volumes are limited.

T4 RNA Ligase 1 catalyzes the ligation of a 5´ phosphoryl-terminated nucleic acid donor to a 3´ hydroxyl-terminated nucleic acceptor through the formation of a 3´ → 5´ phosphodiester bond, with hydrolysis of ATP to AMP and PPi. Substrates include singlestranded RNA and DNA as well as dinucleoside pyrophosphates (1).
