A competitive inhibition radioimmunoassay has been developed for quantitative analysis of the HBsAg-binding polymerized human albumin. Based on this assay, we have shown that specific binding for glutaraldehyde polymerized albumin is at least 1,000 fold stronger than human albumin polymerized by other procedures such as heat, aging and carabodiimide cross-linking. The specific binding site for polymerized albumin is localized on the pre-S gene product of HBsAg. An assay procedure for antibody activity to polymerized albumin has been developed.
