Description

The B-Ly7 monoclonal antibody reacts with human CD103, the alpha E integrin. CD103 non-covalently associates with integrin beta 7. 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. Applications Reported: B-Ly7 has been reported for use in flow cytometric analysis. Applications Tested: This B-Ly7 antibody has been pre-titrated and tested by flow cytometric analysis of 2-3 day PHA-activated human peripheral blood cells. This can be used at 5 uL (0.4 ug) per test. A test is defined as the amount (ug) of antibody that will stain a cell sample in a final volume of 100 uL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. NovaFluor dyes are not compatible with DNA intercalating viability dyes. Invitrogen LIVE/DEAD Fixable Dead Cell stains are recommended for use with NovaFluor dyes. Use 5uL of CellBlox Blocking Buffer per stained cell sample containing 10^3 to 10^8 cells. Excitation: 552 nm; Emission: 718 nm; Laser: 561 nm (Yellow) Laser

CD103 (ITGAE, Integrin alpha E) is molecule that is expressed on mucosa-associated T lymphocytes and activated cells and on subet of TGF beta -1 cells. In particular, CD103 includes a 150kDa alpha chain and a 120kDa beta chain. CD103 is expressed by 0.5 to 2% of resting lymphocytes in peripheral blood and lymphoid organs. CD103 antibody stains a few bone marrow cells and, rarely, peripheral blood lymphocytes. CD103 is part of the integrin family which are heterodimeric integral membrane proteins composed of an alpha chain and a beta chain. ITGAE encodes an I-domain-containing alpha integrin that undergoes post-translational cleavage in the extracellular domain, yielding disulfide-linked heavy and light chains. In combination with the beta 7 integrin, CD103 protein forms the E-cadherin binding integrin known as the human mucosal lymphocyte-1 antigen. CD103 is preferentially expressed in human intestinal intraepithelial lymphocytes (IEL), and in addition to a role in adhesion, it may serve as an accessory molecule for IEL activation. Diseases associated with CD103 dysfunction include hairy cell leukemia and splenic marginal zone lymphoma.
