LigaFast™ Rapid DNA Ligation System

The LigaFast™ Rapid DNA Ligation System is designed for the efficient ligation of sticky-ended DNA inserts into plasmid vectors in just 5 minutes (blunt-ended inserts in as little as 15 minutes). Rapid ligation is based on the combination of T4 DNA Ligase with a unique 2X Rapid Ligation Buffer. The LigaFast™ System is designed to eliminate any further purification prior to transformation of ligated DNA. The specially formulated 2X Rapid Ligation Buffer requires no additional ATP or Mg²⁺ addition prior to use.

The LigaFast™ System is Blue/White Cloning Qualified, providing a higher level of quality control for enzymes used in cloning applications.

Storage Buffer: 10mM Tris-HCl (pH 7.4 at 25°C), 50mM KCl, 1mM DTT, 0.1mM EDTA and 50% glycerol.

QC Tests: Activity, SDS-PAGE/purity, DNase, endonuclease, RNase, blue/white cloning assay.

Unit Definition: 0.01 Weiss unit of T4 DNA Ligase is the amount of enzyme required to catalyze the ligation of greater than 95% of 1μg of λ/HindIII fragments at 16°C in 20 minutes.
