Abstract
Modifications of lymphoid cells with dinitro-2,4 phenylsulfonic acid (DNBS) or trinitro-2,4,6 phenylsulfonic acid (TNBS) have been studied. TNBS action always produces an electrophoretic mobility increase in relation with the amount of amino-groups, according to the cell type. DNBS action produces an electrophoretic mobility increase for B cells of spleen and a decrease for T cells of spleen and thymic cells. The hydrophobic fluorescent probe 1-anilino-8-naphthalene sulphonate used to study conformational changes of cells revealed a slight fluorescence decrease for TNP-modified cells and an important fluorescence increase for DNP-modified cells.
