General description
Integrins are a family of dimeric proteins that mediate cell-cell and extracellular matrix adhesion. Each VLA subtype (VLA-1, VLA-2, VL-3, VLA-4, VLA-5) is composed of a distinct alpha subunit noncovalently associated with a common beta subunit, as an alpha-beta dimer. Integrin VLA-3 (very late antigen, alpha-3/beta-1) is a cell surface receptor that binds to fibronectin, laminin, collagen type I and VI. VLA-3 is typically restricted in normal tissue but is widely expressed in many cultured tumor cells and correlates with the degree of invasiveness of malignant melanoma cells.
Specificity
Recognizes an epitope related to the VLA-3 complex (alpha-3/beta-1 integrin). Specificity was determined by immunoprecipitation from a detergent extract of 35S-methionine labeled KJ29 cells.
Immunogen
Human renal carcinoma cell line (KJ29).
Application
Immunohistochemistry (works on Acetone-fixed paraffin-embedded tissues)
ELISA/RIA
Immunoprecipitation. When immunoprecipitated samples are run on SDS-PAGE under a) non-reducing conditions, two bands will be detected with an apparent molecular weight of 110 and 150kDa; and b) reducing (2% B-ME) conditions, a single molecular species of 130kDa is detected. Under reducing conditions both alpha3 and beta1 subunits run with the same apparent molecular weight.
Optimal working dilutions must be determined by end user.
