title: Separation of rat T and B lymphocytes by density gradient electrophoresis.
abstract: Density gradient electrophoresis has been employed for the preparative separation of T and B lymphocytes from rat spleen and peripheral blood. The high mobility cells were found to be predominantly T lymphocytes, as determined by their response to phytohemagglutinin and the relative absence of immunoglobulin-positive cells. The low mobility cells were predominantly B cells, as determined by the high percentage of immunoglobulin-positive cells and the total lack of response to PHA, an exclusive T cell mitogen. A better separation of peripheral blood T and B lymphocytes was achieved than with spleen T and B cells.
