ABSTRACT:
This invention provides an expression vector encoding a CD4-gamma2 chimeric heavy chain homodimer. This invention also provides an expression vector encoding the heavy chains of a CD4-IgG2 chimeric heterotetramer. Finally, this invention provides an expression vector encoding the light chains of a CD4-IgG2 chimeric heterotetramer.
