Monoclonal antibody, cell line and immunoassay for ractopamine

Abstract

A hybridoma cell line has been produced for secreting a monoclonal antibody that binds ractopamine and is effective to detect ractopamine levels of about 1 ng/mL or lower. This monoclonal antibody may be used for the detection and quantitative determination of trace amounts of ractopamine in samples, especially in animal tissue, body fluids and feed material.
