ABSTRACT
Spleen cells from BALB/c mice immunized with free native human chorionic gonadotropin hormone beta-subunit (beta hCG) were fused with mouse myeloma cells (P3/X63-Ag8) and one hybridoma secreting monoclonal antibodies (MAbs), was obtained. This hybridoma specifically recognizes beta hCG and does not cross-react with other human glycoprotein hormones, such as luteinizing hormone (LH), follicle-stimulating hormone (FSH), thyroid-stimulating hormone (TSH), and human chorionic gonadotropin (hCG). The MAb was of the IgG(1) subclass and ascitic fluid from this hybridoma was purified by affinity chromatography on Protein A-Sepharose CL-4B column to isolate the IgG(1) active fraction. The affinity constant of this MAb was 1.5 x 10(10)M(-1).
