Application Notes

F124 was used as a solid-phase coating for RIAs detecting HBV particles, resulting in particle immobilisation by binding the pre-S2 epitope of the surface antigen (Budkowska et al, 1986). An scFv-formatted version of F124, comprising the same VH and VL sequences, showed dose-dependent binding to, and competitive blocking of IgG and Fab against, r-HBsAg in an ELISA (Passafiume et al, 1998). Size-exclusion HPLC indicates that, while the scFv monomer shows no tendency to aggregate at low concentrations, equilibrium is achieved at a monomer/dimer ratio of 3:1 at high protein concentrations.

Short Description

This chimeric human antibody was made using the variable domain sequences of the original Mouse IgG1 format, for improved compatibility with existing reagents, assays and techniques.
