[Cellular retinol-binding protein from the mucous intermediate zone of the glandular stomach of chickens].

A protein which specifically binds [3H]retinol in vitro and has a sedimentation coefficient of 2S was isolated from the soluble fraction of chicken glandular stomach intermediate zone mucosa cells and purified to homogeneity. The purification procedure included gel filtration through Sephadex G-75 and G-50 and ion-exchange chromatography on DEAE-cellulose. The properties of the protein were compared to those of the retinol-binding protein from rat liver.
