M. Galleni et al., A NEW, HIGHLY SENSITIVE METHOD FOR THE DETECTION AND QUANTIFICATION OF PENICILLIN-BINDING PROTEINS, Biochemical journal, 291, 1993, pp. 19-21
A new method for the identification and quantification of penicillin-b
inding proteins is described which uses fluorescein-coupled penicillin
s. It allows the rapid detection of 0.2 pmol with the naked eye and 2
fmol with the help of an A.L.F. automatic DNA sequencer. Direct labell
ing can also be performed on whole bacterial cells.
