We describe a method for producing polyclonal antibody (PAb) against peptide antigen (the epitope region of cytochromes P450 1A2 and 3A4, HA tag, FLAG tag, and c-myc tag) using a polymer bead as a carrier. Carboxylated polystyrene beads (0.05, 0.5, 1, and 2 microm diam) were conjugated with the peptide, which is known as an epitope region, using a chemical cross-linker and injected into rabbits with adjuvant. By immunizing the animals intradermally twice at two week intervals, an immunoblot assay with anti-sera showed the efficient generation of the PAb.
