Use Exalpha's 3 color CD markers to add flexibility to your current single laser system capabilities. The CD3 epitope is expressed on the epsilon chain of the CD3/T cell antigen receptor (TcR) complex. CD3 is present on 65-85% of thymocytes and has a mitogenic effect on peripheral blood T cells. CD3 indentifies human T cells expressing the 22-28,000 M.W surface antigen. CD19 identifies human B cells associated with 10% of peripheral blood lymphocytes. CD19 identifies lymphocytes expressing the 95,000 M.W. surface antigen. CD45 identifies all human leucocytes, lymphocytes, monocytes, polymorphonuclear cells, eosinphils and basophils in peripheral blood expressing the 180-220K M.W. T200 family surface antigen. CD45 is also present on thymus,spleen, tonsil and progenitor cells in bone marrow.
