The predominant surface glycoproteins of thymocytes and lymphocytes.

The surfaces of thymocytes and T and B lymphocytes differ markedly in their predominant glycoprotein constituents. Amino acid sequence studies show that a surprising number of the cell surface molecules have homologies with immunoglobulins. Analysis of carbohydrate shows major differences between glycoproteins on the same cell and between the same (or closely related) glycoproteins on the different cell types.
