Anti-CD45RA Antibody, Clone MEM 56

Description

• General description: CD45 is a receptor-tyrosine phosphatase required for antigen-induced signaling in T-cells and B-cells; its substrates are unknown. Interestingly, it associates with several Src-family tyrosine kinases, which are inhibited by tyrosine phosphorylation in their c-termini, suggesting a mechanism for signaling by CD45.
• Specificity: This antibody recognizes the 220 kDa molecular weight component of the leucocyte common antigen complex expressed on some CD4+ T lymphocytes, B lymphocytes and CD8+ lymphocytes. The CD45R+/CD4+ lymphocytes functionally exert suppressor/inducer activity in in vitro assay systems. Antigen distribution: B-cells (lg+) >95% T-cells (E+) 70 + 10% Peripheral blood lymphocytes 68 + 8% T-cells (CD4+) 50 + 10% Monocytes 50 + 20% Thymocytes <5% Granulocytes <1%
