3 Method Overview

Radioreceptor analysis is based on the binding of drug functional groups to microbial receptor sites, which share functions with certain classes of antibiotics. Group-related, this specificity of the application of the receptor allows for multi-residue analysis of a certain class of antibiotics. In this method, the macro ring remaining in the sample After the lactone drug is extracted and diluted, it competes with the [14C]-labeled erythromycin to bind to a specific receptor site, and after reacting at a certain temperature, Centrifugation to remove unbound macrolides, and finally adding scintillation fluid to determine [14C] decay of beta-particle radioactivity cpm (countperminute). The measured cpm value is inversely related to the amount of macrolide antibiotic residues in the sample.
