Tenascin antibody [BC-24],Genetex,GTX26393

Tenascin (TN)(Erickson and Bourdon 1989, Erickson 1993) is a high molecular weight, multifunctional, extracellular matrix glycoprotein, expressed in association with mesenchymal-epithelial interactions during development and in the neovasculature and stroma of undifferentiated tumors. It has been described under a variety of names: cytotactin, hexabrachion protein, J1-200/220, myotendinous antigen (MI), neuronectin (NEC1) and glioma mesenchymal extracellular matrix (GMEM). The TN molecule is a disulfide-linked hexamer. Human TN has 3 subunits of 190, 200 and 220 kD. It is primarily made up of 14.5 epidermal growth-factor-like repeats, 15 units similar to the fibronectin type-III-homology repeat and, at the C-terminus, has a sequence with homology to the globular domain of the beta and gamma chain of fibrinogen. Monoclonal antibody reacting specifically with tenascin is an essential tool for the localization, identification and studies on the role of the molecule in epithelial-mesenchymal and neuronal-glial interactions (Castellucci et al. 1991, Balza et al. 1993).
