These single-color reagents are of value to the study of activated lymphoid cells in normal and pathological specimens.CD25 is strongly expressed on the surface of T cells activated by antigens, mitogens (phytohemagglutinin (PHA), concanavalin A (Con-A), pokeweed mitogen (PWM)), Staphylococcus aureus, viruses (HTLV-I, HTLV-II, Epstein-Barr virus), and is also expressed on B cells stimulated with anti-IgM and on monocytes/macrophages stimulated with lipopolysaccharide. In normal peripheral blood a variable staining of T lymphocytes is observed.Further information and references to relevant literature are available in the product’s Instructions For Use.
