title: [Detection and isolation of glycoproteins and nuclear proteins in the bovine brain].
abstract: Using ammonium sulphate precipitation, ion exchange chromatography and preparative isoelectrofocusing, 9 organ-specific glycoproteins and 16 specific nuclear proteins were isolated from bovine brain nervous tissue in a homogeneous state. The isolation of proteins was controlled by a solid phase immunoenzymatic analysis. The molecular weight, subunit composition and isoelectric points of the proteins were determined and their ability to interact with immobilized calf thymus DNA and concanavalin A was demonstrated. It was assumed that the multiplicity of specific proteins of brain tissue is a molecular basis which provides for the functional specificity of the nervous tissue at large.
