human tenascin.

General description

Tenascin (TN) 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. Human TN has 3 subunits of 190, 200 and 220 kD. TN has been independently discovered in a variety of species and tissue types, often in the basement membrane or intercellular spaces. The expression of TN is associated with development and growth, both normal and pathological, with restricted distribution in normal adult tissue. It is synthesized by fibroblasts, chondroblasts, osteocytes, smooth muscle cells and glial cells. Human and chicken TN contain an RGD sequence which may function in cell adhesion and it seems likely that TN mediates cell attachment through an RGD-dependent integrin receptor. Mouse TN does not contain an RGD sequence in the third type III repeat implicated in cell attachment, or in any other positions.


The antibody recognizes an epitope within the N-terminal EGF-like (EGF-L) sequence of the molecule. It recognizes all human tenascin isoforms.


Mouse monoclonal clone BC-24 anti-Tenascin antibody is an essential tool for the localization, identification and studies on the role of tenascin in epithelial-mesenchymal and neuronal-glial interactions.
