to obtain structural information on this molecule that can be used for comparison with known immunoglobulins and other surface molecules , we isolated the t cell-derived molecule by affinity chromatography using an antiserum raised against the monomeric fab fragment of a human waldenstrom macroglobulin and subjected the isolated molecule to either proteolysis using enzymes or cleavage with cyanogen bromide , followed by isolation of polypeptides which bore the fab- or heavy chain variable region ( vh ) -related antigenic markers .
