Isolation of 75Se binding protein from hepatic tissues of chick embryos.
Distribution study using 75Se shows that maximum accumulation was in liver tissues after 24h of 75Se administration. Induction of selenium binding protein (Se-P) in hepatic tissues of chick embryo was observed. Chick embryo hepatic Se-P was isolated after 24h of 75Se treatment using Sephadex G-75 column chromatography. Fractions of induced protein shows the presence of maximum concentration of 75Se. This induced protein was found to have an approximate molecular weight of 56 KD on molecular sieve. It also showed an absorbance maxima at 254 nm, which indicates the presence of high concentrations of sulphydryl groups.
