Anti-Integrin alpha-9 (ITGA9) antibody is validated on mouse tissue and can be used for immunofluorescence labeling, IHC, or western blot of materials from rodent and human tissues.

Integrins are transmembrane proteins that facilitate cell-extracellular matrix interactions or focal adhesions. Ligands for Integrins include fibronectin, vitronectin, collagen and laminin. An integrin molecule is composed of two  protein subunits, alpha and beta. Each subunit consists in an extracellular domain, a single transmembrane domain and a cytoplasmic domain.

Integrin alpha-9 protein is encoded by the ITGA9 gene in human. Integrin alpha-9, when bound to the beta 1 chain, forms an integrin that is a receptor for tenascin-C, VCAM1 and osteopontin.
