Two hybridomas which secrete monoclonal antibody (McAb) against polymerized human serum albumin (PHSA) were obtained by the fusion of SP2/0 myeloma cell with immune murine spleen cells. One of the McAb was identified as mouse IgG1, the other was IgM. The titers of these purified McAb was 1:16 364 with passive hemagglutination assay (PHA). After labelling with 125I by chloramine-T method, a solid phase radioimmune assay for detecting the PHSA has yielded in 21 positive results, out of 126 HBsAg positive sera, but 53 HBsAg negative sera were all negative. At present we have not seen any report of PHSA present in circulation. PHSA may be as a bridge bind receptor between HBV and hepatocytes and then initiate infection. The appearance of PHSA in HBsAg positive sera could be the result of the damage of the liver during virus infection. More work should be done for this explanation.
