Establishment of indirect enzyme-linked immunosorbent assay for artificial musk.

Anti-inflammatory component (AIC) known as an important constituent of artificial musk exhibits bioactive effects on many pharmacological models. This study describes an immunochemical assay for the quality control of artificial musk in traditional Chinese medicine using an enzyme-linked immunosorbent assay. A polyclonal antibody against AIC was produced by rabbit. The method, at an effective measuring range of 3.13-200 ng/ml of AIC, 3 ng/ml limit of detection, and no cross-reaction with natural musk, successfully detected artificial musk in many traditional Chinese prescriptions containing artificial musk. The results demonstrated that a novel and reliable assay system for detection of artificial musk was generated.
