Mouse anti Tenascin CCatalog number: MUB2028P
Immunohistochemistry (frozen & paraffin)
Tenascin is a high molecular weight, multifunctional, extracellular matrix glycoprotein expressed in association with mesenchymal-epithelial interactions during development. It has been described under a variety of names, i.e. cytotactin, hexabrachion protein, J1, myotendinous antigen and glioma mesenchymal extracellular matrix. In undifferentiated tumors it is also detectable in the neovasculature and stroma. The tenascin molecule is a disulfide-linked hexamer. The expression of tenascin is associated with development and growth, both normal and pathological, whereas the distribution in normal adult tissue is restricted. For example, this extracellular matrix protein is implicated in guidance of migrating neurons as well as axons during neural development as well as neuronal regeneration. In in vitro studies it promotes neurite outgrowth from cortical neurons grown on a monolayer of astrocytes. The cellular ligands for tenascin include integrins alpha-8/beta-1, alpha-9/beta-1, alpha-V/beta-3 and alpha-V/beta-6.
T2H5 is a mouse monoclonal IgG1 antibody derived by fusion of mouse myeloma cells with spleen cells from a BALB/c mouse immunized with full length native tenascin protein purified from a homogenate of a human mammary tumour specimen.
Each vial contains 100 µl 1 mg/ml purified monoclonal antibody in PBS containing 0.09% sodium azide.
Formulation: Each vial contains 100 µl 1 mg/ml purified monoclonal antibody in PBS containing 0.09% sodium azide.
In immunoblotting assays on an extract of a human osteosarcoma cell line (U2OS) T2H5 recognizes a 265 kDa protein. Tenascin C contains an exstensive number of potential glycosylation sites, which may explain its migration at a higher molecular weight than predicted. Human tonsilar tissue can be used as a positive control in immunocytochemistry and immunohistochemistry.
T2H5 is suitable for immunoblotting, immunocytochemistry, and immunohistochemistry on frozen and paraffin-embedded tissues. Optimal antibody dilution should be determined by titration; recommended range is 1:100 – 1:200 for immunohistochemistry with avidin-biotinylated horseradish peroxidase complex (ABC) as detection reagent, and 1:100 – 1:1000 for immunoblotting applications.
The antibody is shipped at ambient temperature and may be stored at +4°C. For prolonged storage prepare appropriate aliquots and store at or below -20°C. Prior to use, an aliquot is thawed slowly in the dark at ambient temperature, spun down again and used to prepare working dilutions by adding sterile phosphate buffered saline (PBS, pH 7.2). Repeated thawing and freezing should be avoided. Working dilutions should be stored at +4°C, not refrozen, and preferably used the same day. If a slight precipitation occurs upon storage, this should be removed by centrifugation. It will not affect the performance or the concentration of the product.
