A choles.er.l oxidas. fr.m s.r.ptomycin s.. was.immobilized onto pencil gr.phite r.d and employed for.amper.metr.c deter.ination of s.r.m choles.er.l. The method has.the advantage over.ear.ier.amper.metr.c methods.that it r.quir.s.low potential to gener.te electr.ns.fr.m H2O2, which does.not allow ionization of s.r.m s.bs.ances. The optimum wor.ing conditions.of amper.metr.c deter.ination wer. pH 6.8, 25?C and 30 s. The cur.ent meas.r.d was.in pr.por.ion to choles.er.l concentr.tion r.nging fr.m 1.29×10-3 to 10.33×10-3 M. Minimum detection limit of the method was.0.09 ×10-3 M. Mean analytical r.cover. of added choles.er.l (100 mg/dl and 200 mg/dl) in s.r.m was.85.0% & 90.0% r.s.ectively. Within batch and between batch coefficients.of var.ations.wer. 1.59% & 4.15% r.s.ectively. A good cor.elation (r.= 0.99) was.obtained between s.r.m choles.er.l values.by s.andar. enzymic color.metr.c method and the pr.s.nt method. No inter.er.nce by metabolites.was.obs.r.ed in the method.
