Anti-Integrin α3 Antibody

Integrins are a family of dimeric, transmembrane proteins that mediate cell-cell and extracellular matrix adhesion. Signals transduced by integrins play a role in many biological processes, including cell growth, differentiation, migration and apoptosis. The integrin family is composed of at least 19 alpha and 8 beta subunits that form over twenty different alpha-beta non-covalently bound dimeric combinations on the cell surface. Both of the subunits contribute to the binding of the ligand. The alpha-3 subunit (CD49c) is highly concentrated in epithelial cells where it strongly adheres to Laminin-5 and Laminin-5 induced rapid adhesion can be blocked by antibodies against the alpha-3 integrin subunit. The alpha-3 subunit exists in two different splice variants, denoted as "A" and "B". The only difference that results from this differential splicing is a total change in the cytoplasmic domain, while the extracellular domain stays the same. Knock-out mice lacking this subunit show prenatal lethality and abnormalities in the kidneys.

Reactivity with other species has not been determined.
Integrin alpha3. Specificity determined by immunoprecipitation from a detergent extract of 35S-methionine labeled neuroblastoma cells. No cross-reactivity to alpha1, alpha2, alpha4, alpha5, alpha6, or alphaV integrins.

A synthetic peptide (CRIQPSETERLTDDY) derived from the COOH terminal sequence located in the cytoplasmic domain of the human alpha3 integrin subunit.

Detect Integrin α3 using this Anti-Integrin α3 Antibody validated for use in ELISA, IF, IH, IP, RIA & WB.
ELISA/RIA:
A 1:1,000 dilution of a previous lot was used in Enzyme-linked Immunosorbent Assay/Radioimmunoassay.

Immunoprecipitation:
5 µL of a previous lot precipitated alpha3/beta1 from 5 x 106 cells (Sherry, D.M., 2001).

Immunohistochemistry/immunofluorescence:
1:500 dilution of a previous lot was used, suggest use on acetone-fixed tissue.

Western Blot Analysis:
1:500 dilution of a previous lot was used.

Optimal working dilutions must be determined by end user.

Routinely evaluated by Western Blot on A431 lysates.

Western blot: 1:500 dilution of this lot detected INTEGRIN ALPHA 3 on 10 μg of A431 lysates.
