CD4/L3T4 is a type I transmembrane glycoprotein expressed on most thymocytes and the helper/inducer subpopulation of mature T lymphocytes of all mouse strains tested (1,2). CD4 has also been detected at low density on pluripotent hematopoietic stem cells, bone marrow myeloid precursors, and intrathymic lymphoid...

CD2, also known as leukocyte function-associated antigen-2 (LFA-2), is a member of the immunoglobulin superfamily of cell adhesion molecules. It is expressed on the surface of > 95% of thymocytes, and essentially all B cells, T cells and NK cells (1-3). In the mouse, CD2 is the receptor for CD48 (3). CD2 is thought...
