Popis: A differential paper chromatographic assay for the components of the gentamicin complex, designated as C 1 , C 1a , and C 2 , is described. The gentamicins are separated on paper strips with the lower phase of a solvent mixture consisting of chloroform, methanol, and 17% ammonium hydroxide (2: 1: 1, v/v). After chromatographic separation, the paper strips are plated against Staphylococcus aureus ATCC 6538P, and the zones of activity are quantified against known standards.
