This kit has been developed as a reagent for research purposes to
detect respective subtypic determinants, d, y, r, and w, in hepatitis B
surface antigen (HBsAg) positive samples for identification of
HBsAg subtypes such as adr, adw, ayr and ayw. Detection of
subtypic determinants is based on the solid-phase sandwich EIA
(Enzyme Immuno Assay). 96 wells of the microplate are coated
with monoclonal antibody against the common determinant a of
HBsAg. HBsAg in samples dispensed to wells is caught on the
solid phase and their subtypic determinant, d, y, r, or w, is detected
by peroxidase-labeled monoclonal antibody against corresponding
determinant.
