Brand:  Invitrogen™ 15224041

Product Code. 10443242

Includes: T4 DNA Ligase is supplied with a vial of 5X reaction buffer [250mM Tris-HCl (pH 7.6), 50mM MgCl₂, 5mM ATP, 5mM DTT, 25% (w/v) polyethylene glycol-8000].

Description

The unique T4 DNA Ligase buffer optimizes ligation, which can be performed in 5 minutes. Single-stranded nucleic acids are not substrates for this enzyme.

Unit Definition: One unit catalyzes the exchange of 1nmol ³²P-labeled pyrophosphate into ATP in 20 min. at 37°C. (One unit is equal to approximately 300 cohesive-end ligation units.)

Unit Reaction Conditions: 66mM Tris-HCl (pH 7.6), 6.6mM MgCl₂ , 10mM DTT, 66μM ATP, 3.3μM ³²P-labeled pyrophosphate, and enzyme in 0.1mL for 20 min. at 37°C.
