Monoclonal Mouse Purified B IH IC
Nestin, a large intermediate filament protein (class Type VI), is expressed during development and in myotendinous and neuromuscular junctions. Nestin expression is restricted, typically disappearing by E18. Nestin is thought to be a reasonable neuronal marker; however, recent studies have found nestin expression in other cell types such as endothelial cells (Mokry and Nemecek, 1998). Nestin identifies the most primative neuroepithelium, but also identifies many other embryonic tissues. So, it is not specific for CNS. Nestin expression is seen in almost all GBMs (Glioblastoma mulitformes) and many melanomas (both primary and metastatic), but not in any metastatic carcinomas.
Catalog #N2060-10
ApplicationsSuitable for use in Immunohistochemistry, Western Blot and Immunocytochemistry. Other applications have not been tested.
Recommended DilutionsImmunohistochemistry (Frozen or paraffin): 1:20-1:200. Perfuse tissue with 4% paraformaldehyde, pH 7.4 for light microscopy or with either 4% paraformaldehyde, pH 10 or 4% paraformaldehyde with 0.1% glutaraldehyde, pH 7.4 for EM.
Western Blot: 200-220kD in reducing gels of newborn rat or mouse cell extracts. Prepare samples by boiling in 4 volumes of 125mM Tris, pH 6.8, 10% 2-mercaptoethanol, 10% glycerol, 4.6% SDS. 5% PAGE gels are suggested. Block membranes with milk or BSA. Do not dilute primary antibody in buffer containing milk. Freezing and thawing of samples or samples not stored at -70°C will show breakdown of nestin sometimes into multiple fragments.
Immunocytochemistry: 1:20-1:200. Fix cells in 4% paraformaldehyde buffered with 50mM sodium borate, pH 9.5.
Optimal dilutions to be determined by the researcher.
Recommended Positive ControlMouse embryonic brain tissue
