A STUDY ON THE STRUCTURAL PROTEIN OF THE VITREOUS BODY (VITROSIN)
A method is described for the isolation of a structural protein of the vitreous body, which has been named vitrosin. The analyses show that vitrosin is a viscous, thixotropic, fibrous protein. Electron micrographs reveal that vitrosin particles are long fibrils, averaging 250 A in width. The isoelec...

| Sumario: | A method is described for the isolation of a structural protein of the vitreous body, which has been named vitrosin. The analyses show that vitrosin is a viscous, thixotropic, fibrous protein. Electron micrographs reveal that vitrosin particles are long fibrils, averaging 250 A in width. The isoelectric point was found to be around pH 5.5 and the shrinkage temperature 60°C. Vitrosin is composed of a protein-carbohydrate complex. It contains cystine and the aromatic amino acids in low quantities. Hexosamine could not be detected in the complex. |
