Recombinant Enzymes
At NEB, enzyme production is linked to basic research in the cloning and overexpression of restriction/modification
enzyme systems. This enables us to introduce substantial cuts in reagent costs and unsurpassed improvements in
product quality. At NEB, over 150 enzyme systems have been cloned, many completely and some partially. Presently,
NEB supplies more than 230 restriction enzymes, over 150 of which are available in recombinant form, as well as
numerous recombinant polymerases and modifying enzymes for a wide variety of applications.
