REDUCING NON-SPECIFIC BINDING IN IMMUNOASSAYS PERFORMED ON POLYMERIC SOLID PHASES

摘要

Water-soluble polymer is added to the liquid phase in a heterogeneous immunoassay of serum, the polymer having monomers in common with monomers of the solid phase surface. This reduces non-specific binding of IgG's from the serum to the solid phase surface and thereby reduces the occurrence of false positive readings in the immunoassay.
