The in vitro effect of horse anti-human lymphocyte globulin on the electrophoretic mobility of human lymphocytes and platelets.

In accordance with earlier results the electrophoretic mobility of lymphocytes is decreased by horse anti-human lymphocyte globulin (AHLG), which correlates with the results of the rosette inhibition test. Under the influence of AHLG, the distribution of the electrophoretic mobilities of lymphocytes shows a characteristic change. In some of the AHLG samples, the antilymphocyte action is accompanied by an antithrombocyte effect. The resulting decrease in the electrophoretic mobility of platelets correlates with the thrombocytopenic effect in vivo. The variation of pH or ionic strength leads to changes of the AHLG effects. The in vivo influence of AHLG on the distribution of the electrophoretic mobility of peripheral blood lymphocytes and platelets is discussed.
