| Abstract: | Objective To optimize the quality control system of recombinant human erythropoietin(rHuEPO).Methods Determine the in vivo bioactivity of rHuEPO by full-automatic reticulocyte analyzer.Compare the isoelectric focusing(IEF)electrophoretic profiles of rHuEPO under various conditions as well as the determination results of protein and residual bovine serum albumin(BSA)contents by various methods.Identity test and other control tests were performed according to the requirements in Chinese Pharmacopoeia(Volume Ⅲ,2005 edition).Results Full-automatic reticulocyte analyzer was simple and reliable for the determination of in vivo bioactivity of rHuEPO.The addition of urea into running gel increased the definiting power of bands on IEF electrophoretic profile.BSA ELISA kit was suitable for accurate quantitative analysis of residual BSA in rHuEPO.Western blot was suitable for identity test on final product of rHuEPO.Conclusion A feasible system for quality control of rHuEPO was developed. |
