Anti-Human CD103 (Integrin alpha E) FITC

Description: The B-Ly7 monoclonal antibody reacts with human CD103, the α_E integrin. CD103 non-covalently associates with integrin β₇. CD103 is expressed mainly on intraepithelial lymphocytes and a small subset of peripheral lymphocytes. CD103 is also expressed by hairy cell leukemia (HCL) and by some chronic B cell lymphocytic leukemias. In vitro stimulation of human T cells with mitogens induces upregulation of CD103. Epithelial cell antigen, E-cadherin, binds to CD103 and mediates homing of lymphocytes to the intestinal epithelium.
