Abstract

An indirect competitive enzyme-linked immunosorbent assay (ELISA) was developed using rabbit polyclonal antibodies against the eremomycin-glucose oxidase conjugated antigen. This technique allows the glycopeptide antibiotic eremomycin to be determined both in aqueous solutions (with a sensitivity as high as 0.1 ng/ml) and in blood plasma. The cross-reactivity of the antibodies with vancomycin was 0.4% of that for eremomycin, while teicoplanin was almost not recognized. Experiments with blood plasma samples diluted 1: 10 showed that the assay was linear over the concentration range 1–30 ng/ml and that the variation coefficient did not exceed 10%. The high sensitivity and selectivity of this test make it suitable for pharmacokinetic studies and drug monitoring analysis.
