An electrophoretic analysis of sheep plasma protein labeled with Na2 75SeO3 in vivo.
Following an intravenous injection of 75Se, sodium selenite plasma samples were analyzed by two-dimensional electrophoresis. 75Se was detected by indirect autoradiography. From 0.5 to 53 hr postinjection of 75Se, 21 75Se peptides were detected. Both the isoelectric points and molecular weights of these peptides are reported. The molecular weights of the peptides ranged from 20,000 to 70,000 daltons.
