it is suggested that the ability of the polyclonal anti-cd3 antisera to detect t cells in paraffin sections is due to the presence in these sera of antibodies against fixation resistant epitopes on cd3 antigen , and that immunisation with purified denatured preparations of other white cell associated antigens may broaden the range of antibodies suitable for the phenotypic analysis of leucocytes in routine histological samples .
