High fidelity polymerases are everywhere—but why would you need a high fidelity ligase? And what do we even mean by “fidelity” when we’re talking about ligation? In this webinar, NEB Scientist and ligase expert Greg Lohman discusses mismatch ligation by DNA ligases and the molecular diagnostics applications that depend on the use of high-fidelity DNA ligases like NEB’s HiFi Taq DNA Ligase to detect single base differences in DNA.
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.
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.
Find out how the downstream application dictates the best reaction conditions for ligation.
The optimal reactant ratio is contingent upon the downstream application.
