Research on the determination of molecular weight distribution of anti-HBV placenta transfer factor injection / 中国生化药物杂志

ABSTRACT

Objective To establish the molecular weight distribution of anti-HBV placenta transfer factor injection (PSTF) by electrophoresis, HPLC and MS.Methods Using the methods of SDS-PAGE, HPSEC, MALDI-TOF-MS to test the molecular of PSTF.Results The Molecular was 8000 Da by SDS-PAGE.There were 5026.67,6783.44,7496.42,8736.55 Da components in PSTF by HPSEC.The main component molecular was 2972 Da and the maximum molecular component was 8194 Da.Conclusion HPSEC is simple and rapid to determine the maximum component molecular of PSTF.
