The M290 antibody reacts with the α chain of αIELβ7 integrin. CD103 has a unique and fairly restricted tissue distribution. It is expressed on
almost all intestinal intraepithelial lymphocytes (IEL), on dendritic epidermal T cells (DEC), on subpopulations of peripheral T cells, and on
distinct subsets of fetal, neonatal, and adult thymocytes. E-cadherin is the epithelial-cell ligand for αIELβ7 integrin. The ordered expression of
αIEL during thymocyte development (which occurs under the influence of the thymic epithelium), the high level of expression of αIEL on
those peripheral T cells found in epithelial tissues (IEL and DEC), and the expression of CD103 on a subset of CD8+ lymphocytes responding
to allogeneic epithelial cells suggest that αIELβ7 integrin may have a common role in the interactions of T lymphocytes with epithelia during
T-cell maturation and effector functions. CD103 is thought to play a role in allograft rejection. The M290 antibody is reported to efficiently
inhibit αIELβ7-mediated adhesion in in vitro assays.

注意事项:
1.Since applications vary, each investigator should titrate the reagent to obtain optimal results.
2.Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
3.Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.
4.The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography.
5.The antibody was conjugated with R-PE under optimum conditions, and unconjugated antibody and free PE were removed.
