Product description
Integrin alpha 4 Antibody: The integrin alpha 4 (also known as CD49d and ITGA4) belongs to the integrin alpha chain family of proteins. Integrins are heterodimeric integral membrane proteins composed of an alpha and beta chains. Alpha4 chain associates with either beta1 or beta7 chain. It has been demonstrated that the putative ligand-binding sites of both integrin alpha4beta1 and alpha4beta7 is located on the alpha4 chain. These ligands included Madcam, VCAM, and fibronectin. Madcam is known as the principal ligand for integrin alpha4beta7. Recently it was also demonstrated that HIV-1 envelope can mimic Madcam by binding to and signaling though integrin alpha4beta7, the gut mucosal homing receptor for peripheral T cells.1) Wegener KL and Campbell ID.

Immunogen
Integrin alpha 4 antibody was raised against a 13 amino acid synthetic peptide from near the carboxy terminus of human Integrin alpha 4. The immunogen is located within the last 50 amino acids of Integrin alpha 4.

Tested Applications
ELISAWB
Integrin alpha 4 antibody can be used for the detection of Integrin alpha 4 by Western blot at 1 μg/mL. Despite its predicted molecular weight, Integrin alpha4 will often run at higher molecular weight in SDS-PAGE.:

Tissue Specificity
At least two isoforms are known to exist. The immunogen to this antibody is outside of the Integrin alpha4 recombinant protein fragment and thus will not recognize it.
