New England Biolabs' (NEB) popular web tools, Double Digest Finder and Enzyme Finder, are now available for the iPhone™ and iPod® Touch. These tools to help design restriction enzyme experiments are ...

The biological function of restriction enzymes is derived from the defense of foreign DNA from invading cells. The restriction-modification system of bacteria makes the DNA bases of bacteria to be ...

Fifty-one isolates of Phialophora americana, P. parasitica, P. richardsiae, and P. verrucosa (deuteromycetes) were initially characterized by restriction enzyme mapping of the ribosomal DNA region ...

I remember clearly the first time I made a supervised trip, as an undergraduate student, to the departmental freezer to obtain a precious aliquot of restriction enzyme. Its real value, however, only ...

"We are able to show that caloric restriction slows down aging by preventing an enzyme, peroxiredoxin, from being inactivated. This enzyme is also extremely important in counteracting damage to our ...
