Abstract
Endogenous or deliberately added HBsAg was removed and concentrated for assay from albumin and coagulation factor II, VII, IX and X concentrates as model plasma fractions. The concentrates carry considerable risk of causing hepatitis in transfused patients. The amount of antigen remaining in the fraction was estimated at < 1/10,000 of that detectable by the Ausria II radioimmunoassay and 1/100 of that found infectious when highly contaminated human sera were diluted and injected in chimpanzees. Batch fractionation methods with polyethylene glycol were used. The albumin yield was 96%, and the coagulation factors yield about 90%.This publication has 5 references indexed in Scilit:
