A New Rat Lymphocyte Surface Marker: Characterization and Separation of Cells with Receptors for Helix pomatia Hemagglutinin

Abstract
Thirty-two percent of neuraminidase-treated DA rat spleen lymphocytes and 18% of lymph node lymphocytes possess receptors for Helix pomatia hemagglutinin (HP). Moreover, these HP-receptor-bearing cells can be separated from B cells by affinity chromatography on HP-Sepharose columns. The virtual absence of immunoglobulin (Ig) receptors and the close correlation with reported T-cell content of these lymphoid tissues surest that HP-receptor lymphocytes are probably T cells and that HP may provide a convenient marker, for both the identification and the purification of rat T lymphocytes.
