Nestin (ESTM46, FLJ21841, Intermediate Filament Protein, Nbla00170, Nes)

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.\n\nApplications:\nSuitable for use in Immunohistochemistry, Western Blot and Immunocytochemistry. Other applications have not been tested.\n\nRecommended Dilutions: \nImmunohistochemistry (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.\nWestern 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 degrees C will show breakdown of nestin sometimes into multiple fragments. \nImmunocytochemistry: 1:20-1:200. Fix cells in 4% paraformaldehyde buffered with 50mM sodium borate, pH 9.5.\nOptimal dilutions to be determined by the researcher.\n\nRecommended Positive Control: \nMouse embryonic brain tissue\n\nStorage and Stability:\nMay be stored at 4 degrees C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C. Aliquots are stable for 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
