Background
Integrins are cell adhesion molecules that can mediate bidirectional transfer of signals across the plasma membrane. The cytoplasmic domains of integrin family members interact with components of the signal transduction apparatus within cells. Integrin receptors contain noncovalently associated α and β subunits that consist of a large extracellular region (the ligand-binding domain), a short transmembrane region, and a cytoplasmic domain of varying length. In mammals, at least 17 α subunits and 8 β subunits have been identified and these proteins can heterodimerize to form at least 22 different receptors. The integrin β3 subunit associates with integrin α2 in platelets where this glycoprotein complex acts as a fibrinogen receptor and mediates platelet aggregation. In endothelial cells, integrin β3 complexes with the integrin αV subunit to form the vitronectin receptor. This receptor mediates endothelial cell adhesion to vitronectin, fibrinogen, von Willebrand factor, thrombospondin, laminin, and fibronectin.

Immunogen
Clone M582 was generated from a recombinant protein containing amino acid residues in the extracellular region of human Integrin β1. This sequence has high homology with rat and mouse Integrin β1, and has low homology to other integrin family members.
Buffer and Storage
Mouse monoclonal antibody purified with protein A chromatography is supplied in 100µl phosphate-buffered saline, 50% glycerol,
1 mg/ml BSA, and 0.05% sodium azide. Store at –20°C. Stable for 1 year.
Specificity
This antibody detects a 130 kDa* protein corresponding to the molecular mass of Integrin β1 on SDS-PAGE immunoblots of human MDA-MB-231 cells.

*All molecular weights (MW) are confirmed by comparison to Bio-Rad Rainbow Markers and to western blot mobilities of known proteins with similar MW.
