Purified composition of bispecific molecules and methods of production

摘要

The invention provides a method for producing purified compositions of bispecific molecules each comprising (a) an antigen recognition portion that binds a C3b-like receptor and (b) one or more double-stranded DNA molecules cross-linked to the antigen recognition portion. In particular, the invention provides a method for purifying bispecific molecules using alcohol precipitation. The invention also relates to the purified products of bispecific molecules. The purified compositions of the invention are useful for treating Systemic Lupus Erythematosus (SLE).
