Abstract
ABSTRACT Mabs against HBsAg have been used for structural analyses, development of diagnostic tests, and for antigen immunopurification. Resultant products obtained from current methods of genetic recombination demand reference materials to test their potency, identity, purity, and the biological and immunological specific activity corresponding to their manufacturing processes. In this paper, we present a method for the qualitative and quantitative characterisation of CB.Hep-1 and CB.Hep-4 RM and their stability, in real time, with the required quality to be used as primary reference materials. Among the criteria applied in this study, we considered Mab-specific concentration through ELISA, purity, and total proteins by various methods, quantification of antigen recognition capacity of Mabs through the Ag-Mab absolute- recognition method. Sterility, homogeneity, stability, subclass, and isoelectric focusing were used in the characterisation of the reference materials.
