Abstract

Molecules which are capable of specifically binding to a hepatitis B escape mutant antigenic determinant include monoclonal antibodies secreted by the cell line SMH HBs 145/G/R/I (ECACC 92122312). SMH HBs 145/R/I (ECACC 93052626). SMH HBs 145/G/II (ECACC 93033109) or SMH HBs 145/R/II (ECACC 93033110) and other specific binding molecules cross-competitive with them. Antibodies secreted by the cell lines SM HBs 145/G/R/I and SMH HBs 145/G/R/II bind variant (escape mutant) HBsAG and wild type HBsAG. Antibodies secreted by the cell lines SMH HBs 145/R/I and SMH HBs 145/R/II bind variant but not wild type.
