Abstract: Objective To produce specific monoclonal antibody(mAb)against recombinant human erythropoietin(rHuEPO)for development of higmy efficient methods for erythropoietin detection in biological fluids.Methods rHuEPO was covalently coupled with bovine serum albumin(BSA)and the conjugate was used to immunize mice to produce specific mAb against rHuEPO based on hybridoma technology.The obtained F3-mAb was characterized by enzyme-linked immunosorbent assay (ELISA),SDS-PAGE and Western blot.Results The isotype of F3-mAb Was found to be IgM with an affinity constant of 2.1x108 L/mol.The competitive ELISA using the obtained IgM showed a broader linear range and lower detection limit compared with previous work.Conclusions The modification of rHuEPO was proved to be successful in generating required specific mAb with high avidity to rHuEPO.
