Extra Details:: 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. Applications: Suitable for use in Flow Cytometry, Immunoprecipitation, Immunohistochemistry, Inhibition of cell attachment. Other applications not tested. Recommended Dilutions: Inhibition of cell attachment: inhibits SCC9 cell adhesion to human laminin and laminin GD-2 peptide, but not to EHS laminin, type IV collagen or fibronectin. Does not inhibit SKOV-3 cell adhesion to laminin, fibronectin or type IV collagen. Immunohistochemistry: on acetone-fixed frozen human epithelial tissues including tongue, foreskin and ovary. Not for use on formalin-fixed tissue. Flow cytometry: stains human squamous cell carcinoma (SCC9), ovarian carcinoma (SKOV-3) and umbilical vein endothelium (HUVEC). Stains RKO or K562 cells transfected for CD104 expression. Does not stain monocytes, neutrophils, lymphocytes, T cells, B cells or platelets. Immunoprecipitation: precipitates PAGE bands of 66, 76, 120, 135 and 200kDa (reduced) or 66, 110, 125, 130 and 190kDa (non-reduced) from surface-biotinylated SCC9 cells. Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 12 months after receipt. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
