Restriction enzymes enable a DNA molecule to be cut at a specific location and are essential tools for recombinant DNA technology. Restriction enzymes are classified into three categories: Type I, Type II, and Type III, according to cofactor requirements and characteristics of cleavage sites. The most common type, Type II, cleave DNA at the recognition sequence or at a defined distance from the recognition site.

With 30 years of production experience, our DNA restriction enzymes are unsurpassed in quality and purity. Every lot of our DNA restriction enzymes undergoes stringent quality control tests to ensure that the enzymes are supplied with optimized buffers for maximum activity during digestion reactions.
