the present data suggest [ 1 ] that beta2m and the alloantigenic hl-a polypeptide chain are under separate genetic regulation [ 2 ] , that the cell surface integration of the hl-a antigen-carrying polypeptide chain is independent of the presence of beta2m and [ 3 ] that beta2m does not constitute a membrane component absolutely necessary to the integrity of the cell membrane .
