Cell Structure

The CHEMICON^® Beta Integrin-Mediated Cell Adhesion Array Kit can be used for assessing the presence or absence of specific integrins on the cell surface. This assay can substitute for FACS analysis (3) and is useful for screening human adherent cells for cell surface integrins or for monitoring in vitro cell differentiation or genetic modification of cells.

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.

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.

The experimental and control plates can be stored at 2° to 8°C in the foil pouch up to their expiration. Unused strips may be placed back in the pouch for storage. Ensure that the desiccant remains in the pouch, and that the pouch is securely closed.

Precautions:

· Cell stain contains minor amounts of crystal violet, a toxic substance, which may cause cancer and heritable genetic damage. Handle with caution. Toxic by inhalation and if swallowed. Irritating to eyes, respiratory system and skin.

· Extraction buffer contains alcohol. Avoid internal consumption.
