产品描述 | Penicillin G-d5is intended for use as an internal standard for the quantification of penicillin G by GC- or LC-MS. Penicillin G is a β-lactam antibiotic that is effective mainly for Gram-positive bacteria.1It has MIC90values of 0.03, 1, and 4 µg/ml for penicillin-susceptible, -intermediate, and -resistant strains ofS. pneumoniae, respectively, and 16-128 µg/ml for variousBacteroidesisolates in a broth dilution assay.2,3Formulations containing penicillin G have been used for the treatment of bacterial infections and in livestock production. 1.Demain, A.L.Production of beta-lactam antibiotics and its regulationProc.
