Product Specific Information

Highest antigen sequence indentity to the following orthologs: Mouse (91%), Rat (91%).

This recombinant protein control fragment may be used for blocking experiments with the corresponding antibody, PA5-84409. In IHC/ICC and WB experiments, we recommend a 100x molar excess of the protein fragment control based on the concentration and the molecular weight. Pre-incubate the antibody-protein control fragment mixture for 30 min at room temperature.

Target Information

CD29, also known as ITGB1 or Integrin Subunit Beta 1, is a 110 kDa cell surface glycoprotein widely expressed by various cells, including all leukocytes. It forms non-covalently linked heterodimers with at least six different alpha integrins (CD49a-f), creating VLA-1 through VLA-6 complexes, as well as with CD51. These alpha-beta integrin heterodimers mediate a range of cellular responses, including adhesion, trafficking, proliferation, and differentiation. CD29-containing integrins bind to extracellular matrix proteins such as collagen, laminin, fibronectin, and vitronectin. Some integrins also interact with cellular receptors like VCAM-1 and MadCAM-1. CD29 plays a crucial role in immune cell trafficking from blood to tissue, particularly during leukocyte emigration and extravascular migration. It is involved in regulating tissue damage and disease symptoms related to inflammatory bowel disease. In the presence of anti-tumor drugs, decreased expression of ITGB1 correlates with multidrug resistance in tumor cells. ITGB1-dependent mechanisms enhance cytokine secretion in human airway smooth muscle in response to IL-1beta, facilitated by fibronectin and type I collagen. More than eight beta subunits with numerous splice variant isoforms have been identified in mammals, including two major forms: beta1A and beta1D. Beta1A is present in all tissues except cardiac and skeletal muscle, which express the beta1D variant.
