title: Fluorimetric assay of cephradine, cephalexin and cephaloglycin.
abstract: 1 A simple, rapid and reproducible fluorimetric assay for cephradine, cephalexin and cephaloglycin is described. 2 The method involves addition of formaldehyde which catalyses the formation of fluorescent derivatives. 3 The structural similarities between the side chains of these antibiotics and their identical excitation and emission spectra suggest that they may be forming similar fluorescent derivatives.
