Clone: HP2/6.
Conjugate: APC.
Immunogen: Japanese White Rabbit thymocytes.
Storage Buffer: The reagent is provided in aqueous buffered solution containing protein stabilizer, and ≤0.09% sodium azide (NaN3).
Description: This antibody reacts with the CD4-antigen (T4-antigen), which is expressed on human peripheral T lymphocytes and 80% of thymocytes. The monoclonal antibody reacts on a low level with human monocytes and macrophages. The monoclonal antibody does not react with B-cells , granulocytes and thrombocytes.
60Kd MW lymphocyte surface antigen identified by monoclonal antibodies belonging to the CD4 cluster and present on 54% of peripheral blood T lymphocytes, 50% of thymocytes and some malignant cells of T cell origin. Normal B lymphocytes, monocytes or granulocytes do not express surface CD4 antigen although cytoplasmic expression has been observed in monocytes/macrophages. The CD4 positive T lymphocyte subpopulation has been characterised functionally as comprising helper cells active in amplification of immune responses.
