| Description | β Integrin-mediated Cell Adhesion Array Kit, colorimetric |
| Overview | Introduction: Cell adhesion plays a major role in cellular communication and regulation, and is of fundamental importance in the development and maintenance of tissues. A family of cell surface receptors, the integrins, mediates cell attachment to proteins of the extracellular matrix. Integrins are heterodimer molecules containing an alpha and beta transmembrane glycoprotein subunit that are non-covalently bound together (1-2). Historically, antibodies have been used to determine the integrin profiles of cells by immunoprecipitation, immunofluorescence, immunoblotting, and flow cytometry. These methods are time-consuming, laborious or require sophisticated equipment. The CHEMICON® Beta Integrin-Mediated Cell Adhesion Array kit is designed as a cost effective, efficient method for identification of cell surface integrins. The kit format uses 12 x 8-well removable strips in a plate frame for convenience and flexibility in designing assays. The Integrin-Mediated Cell Adhesion Array can be completed within 1-2 hours, providing a rapid, quantitative assay for the characterization of beta integrin surface expression. In addition, Chemicon continues to provide numerous migration, invasion, and adhesion products including: · Alpha Integrin-Mediated Cell Adhesion Array (ECM530) · Alpha/Beta Integrin-Mediated Cell Adhesion Array Combo Kit (ECM532) · QCM™ 8μm 96-well Chemotaxis Cell Migration Assay (ECM510) · QCM™ 5μm 96-well Chemotaxis Cell Migration Assay (ECM512) · QCM™ 3μm 96-well Chemotaxis Cell Migration Assay (ECM515) · QCM™ 96-well Cell Invasion Assay (ECM555) · 24-well Insert Cell Migration and Invasion Assay Systems · CytoMatrix™ Cell Adhesion strips (ECM protein coated) · QuantiMatrix™ ECM protein ELISA kits Test Principle: The CHEMICON® Beta Integrin-Mediated Cell Adhesion Array uses mouse monoclonal antibodies generated against human beta integrins/subunits (Ãeta1, Ãeta2, Ãeta3, Ãeta4, Ãeta6, alphaVÃeta5, and alpha5Ãeta1), that are immobilized onto a goat anti-mouse antibody coated microtiter plate. The plate is then used to capture cells expressing these integrins on their cell surface; goat anti-mouse antibody coated wells are provided as a negative assay control. Each strip (8 wells total) consists of 7 integrin antibody coated wells and one negative control well (see plate layout on page 3). Experimental cells are seeded onto the coated substrate and incubated. Subsequently, unbound cells are washed away, and adherent cells are fixed and stained. Relative cell attachment is determined using absorbance readings.

| Entrez Gene Number |

| Entrez Gene Summary | Integrins are heterodimers comprised of alpha and beta subunits, that are noncovalently associated transmembrane glycoprotein receptors. Different combinations of alpha and beta polypeptides form complexes that vary in their ligand-binding specificities. Integrins mediate cell-matrix or cell-cell adhesion, and transduced signals that regulate gene expression and cell growth. This gene encodes the integrin beta 4 subunit, a receptor for the laminins. This subunit tends to associate with alpha 6 subunit and is likely to play a pivotal role in the biology of invasive carcinoma. Mutations in this gene are associated with epidermolysis bullosa with pyloric atresia. Multiple alternatively spliced transcript variants encoding distinct isoforms have been found for this gene. |
