Tenascin III-6, III-7

Tenascin is a large glycoprotein that forms disulfide-linked hexamers. Tenascin is made up of a series of repeated structural domains including EGF-like repeats, fibronectin type III repeats, and a region homologous to fibrinogen. Splice variants of tenascin differ in their number of fibronectin type III repeats. Tenascin is expressed in distinctive spatial and temporal patterns in most embryonic tissues at sites of tissue remodeling and cell migration. There is little expression of tenascin in adult tissues except, again, at sites of tissue remodeling and cell migration such as surrounding tumors, in healing wounds, and in branching or damaged blood vessels. \nTenascin binds to several cell-surface receptors and mediates cell-substrate adhesion. Nevertheless, tenascin is frequently referred to as an anti-adhesion molecule because for a variety of cell types the presence of tenascin inhibits adhesion to other ECM proteins present. This effect occurs because the binding of tenascin to certain receptors inhibits cell spreading and thereby blocks the stabilization of adhesion that results from cell preading in vitro assays\n\nApplications: \nSuitable for use in Immunohistochemistry and Western Blot. Other applications not tested.\n\nRecommended Dilutions:\nOptimal dilutions to be determined by the researcher.\n\nStorage and Stability:\n May be stored at 4 degrees C for short-term only. For long-term storage and to avoid repeated freezing and thawing, add sterile 40-50% glycerol, aliquot and store at -20 degrees C. Aliquots are stable for at least 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.\n
