Ligation, the process of joining DNA fragments with a DNA ligase, proceeds in three steps. Learn more about ligation with our quick animation.
Ligation of blunt ends and single-base overhangs require optimized reaction conditions.
The optimal reactant ratio is contingent upon the downstream application.
Find out how the downstream application dictates the best reaction conditions for ligation.
Polyethylene glycol (PEG) is an important reagent in ligation reactions, find out why.
NEB continues to develop and produce the most extensive commercially available selection of high-quality, and performance-optimized DNA ligases and ligase master mixes for your ligation needs.
