title: A possible procedure for reducing the immunogenicity of antibody variable domains while preserving their ligand-binding properties.
abstract: It is proposed to reduce the immunogenicity of allogeneic antibody variable domains, while preserving ligand-binding properties, by reducing their antigenicity through replacement of the exposed residues in the framework regions which differ from those usually found in host antibodies. The results of a comparison of representative murine antibody sequences with those of human origin suggest that the number of residues that need to be replaced to "humanize" those antibodies could be small.
