Product Specifications

Immunogen

Recombinant human full-length Tenascin C protein (Uniprot: P24821)

Reactivity Notes

Does not react with Rat.

Localization

Connective tissue matrix

Specificity

In Western blotting, it reacts with two bands of ~MW of 210kDa and 300kDa, identified as two isoforms of Tenascin C. Specificity of this monoclonal antibody is validated by sequential immunoprecipitation with a PAb against Tenascin C. Tenascin C is a multifunctional, disulfide-linkedhexameric extracellular matrix glycoprotein expressed in association with mesenchymal epithelial interactions during development and in the neo-vasculature and stroma of undifferentiated tumors. In adults, it is restricted to certain epithelial-stromal interfaces and increases markedly in hyper-proliferative diseases and in stroma of many neoplasms, including gliomas, breast, squamous and lung carcinomas.

Background: Tenascin C

Tenascin, also known as hexabrachion and cytotactin, is an extracellular matrix protein with a spatially and temporally restricted tissue distribution. It is a hexameric, multidomain protein with disulfide linked subunits of 190 to 240 kD, originally characterized as 'myotendinous antigen.' In the embryo it is present in dense mesenchyme surrounding developing epithelia and in developing cartilage and bone. In the adult, tenascin remains present in tendons and myotendinous junctions in the perichondrium and periosteum, as well as in smooth muscle. 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 kDa. 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).
