General description

Product Source: Purified from embrionic chicken brains.
Tenascin is a large glycoprotein that forms disulfide-linked hexamers. It is made up 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. Tenascin 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.

Physical form

Provided as a liquid in PBS, containing no preservatives.

Storage and Stability

Store at -20°C for up to 12 months. Avoid repeated freeze/thaw.

Analysis Note

Isolated from embryonic chicken brains by chromatographic methods. Contains three characteristic polypeptide chains (220, 200, and 190 kDa) that migrate on SDS gels as a high molecular weight multimer under non-reducing conditions.

A structural and functional model of tenascin was elaborated using recombinant parts of three alternatively spliced tenascin variants and anti-tenascin monoclonal antibodies. The fusion proteins were compared with intact tenascin for their functions and by electron microscopy. A strong cell
