Abstract: Cytokinin binding proteins (CB-protein) which moleculer weight are about 4400 ±100 dalton from cell of Baibaili tobacco callus was purified by affinity chromatography on benzylaminopurin-linked sephrose 4B column. There is CB-protein on cell surface, ribosome, mitochondria, chloroplast and nucleus as well as in cell sap, amount of CB-protein on ribosome is the highest among organdies. We probed into the function of CB-protein.
