T4 DNA Ligase catalyzes the formation of a phosphodiester bond between juxtaposed 5´ phosphate and 3´ hydroxyl termini in duplex DNA or RNA. T4 DNA Ligase joins blunt end and cohesive end termini as well as repairs single stranded nicks in duplex DNA and some DNA/RNA hybrids (1).
Immobilized T4 DNA Ligase (IM T4 DNA Ligase) is a slurry of magnetic beads coated with T4 DNA Ligase to produce a 10 mg/ml solution (50% glycerol) with an effective concentration of 60 cohesive end units (CEU) per microliter of slurry. Following a reaction, enzyme can be removed using a magnet, and can be re-used.
