Formulation
This monoclonal antibody is aseptically packaged and formulated in 0.01 M phosphate buffered saline (150 mM NaCl) PBS pH 7.2 - 7.4 with no carrier protein, potassium, calcium or preservatives added.
Product Preparation
Functional grade preclinical antibodies are manufactured in an animal free facility using only In vitro protein free cell culture techniques and are purified by a multi-step process including the use of protein A or G to assure extremely low levels of endotoxins, leachable protein A or aggregates.
Storage and Handling
Functional grade preclinical antibodies may be stored sterile as received at 2-8°C for up to one month. For longer term storage, aseptically aliquot in working volumes without diluting and store at -80°C. Avoid Repeated Freeze Thaw Cycles.

CyTOF®
Each investigator should determine their own optimal working dilution for specific applications. See directions on lot specific datasheets, as information may periodically change.

Description

Specificity
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.
Background
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.
