Quality Tested by Leinco
For flow cytometric staining, the suggested use of this reagent is ≤0.25 µg per million cells in 100 µl volume. Each lot of this antibody is quality control tested.
Additional Applications Reported In Literature ?
Additional reported applications (for the relevant formats) include:
B The functional grade GOLD (Part No.: I-1141) should be used to block beta7 integrin mediated cell adhesion for In vitro and In vivo studies.
Western Blotting
Each investigator should determine their own optimal working dilution for specific applications. See directions on lot specific datasheets, as information may periodically change.


Clone FIB504 recognizes an epitope on human/mouse integrin β7.
Antigen Distribution
Integrin α4β7 is expressed on subsets of peripheral lymphocytes, thymocytes, and bone marrow progenitors. The αEβ7 integrin is expressed on mucosal T cells, including intraepithelial T lymphocytes (IELs) and lamina propria T cells, subsets of dendritic cells, and regulatory T cells (Tregs)8.
Integrin β7 antibody, clone FIB504, recognizes integrin β7, a 130 kDa membrane glycoprotein of the Ig superfamily. Integrin β7 forms heterodimers with both the α4 (CD49d) and aE (CD103) integrins. α4β7 integrin is expressed on subsets of peripheral lymphocytes, thymocytes, and bone marrow progenitors1,2. It mediates adhesion to mucosal endothelial cells, promoting leukocyte transendothelial migration through interactions with mucosal addressin cell adhesion molecule-1 (MAdCAM-1)3,4. The αEβ7 integrin is expressed on mucosal T cells, including intraepithelial T lymphocytes (IELs) and lamina propria T cells5,6, subsets of dendritic cells7, and regulatory T cells (Tregs)8. It facilitates retention in the gut epithelial layer via interactions with E-cadherin9. Anti-β7 antibodies block both the homing to and retention in the gut of pathogenic T cells10 and are currently under evaluation in a phase 3 clinical trial to treat inflammatory bowel disease11.
