A spectrophotometric assay of beta-lactamase action on penicillins.

Abstract

A new method for measuring the enzymic hydrolysis of the beta-lactam ring in penicillins is described. The change in extinction in the u.v. region is determined. The method is sensitive (50mum-benzylpenicillin can be used) and convenient.
