Abstract

Camelidae are known to produce three subtypes of immunoglobulin G (IgG), two of which are devoid of light chains. Two llamas (Lama glama) were immunised against clenbuterol-bovine serum albumin (BSA). Enzyme-linked immunosorbent assays (ELISAs) for clenbuterol and BSA on the basis of protein A-coated microtitration plates were established to investigate the titre development. Three subclasses of IgG (IgG(1): 29+66KDD, IgG(2): 52KDD, IgG(3): 56KDD) depending on their different binding properties to protein A and protein G could be separated chromatographically. Only IgG(1), which consists of conventional four-chain antibodies, bound to clenbuterol, whereas all forms of heavy-chain antibodies merely bound BSA.
