Improved procedure for the purification of selenoprotein Ph from human plasma.
Selenoprotein Ph, the human analogue of selenoprotein P from rat plasma, was purified from human plasma using Heparin Sepharose chromatography, PEG precipitation, DEAE ion exchange chromatography. RP chromatography, SDS-PAGE and electroelution. SDS-PAGE of the purified protein revealed one broad-selenium containing protein band from 56 to 67 kDa with a selenium maximum at 62 kDa. Using a 7.5% T gel this band was separated into two distinct selenium-containing bands with molecular weights of 61 and 64 kDa.
