Tau proteins are important in the assembly of microtubules. In normal brain, Tau is localized within the axons of the neurons, but in some neuropathological lesions it accumulates within the body of the neuron. Tau proteins are thought to be abnormally phosphorylated in certain disease states. Tau has been immunohistochemically localized to neurofibrillary tangles of Alzheimer’s disease (AD) brains. Tau proteins promote the assembly of tubulin monomers into microtubules and stabilize microtubules. Alternate splicing of Tau mRNA, glycosylation, and differential phosphorylation contribute to the heterogeneity of Tau.||Applications: |Suitable for use in ELISA, Western Blot, Immunoprecipitation, Immunofluorescence, Immunocytochemistry and Immunohistochemistry. Other applications not tested.||Recommended Dilutions:|Western Blot: 1:500|Immunohistochemistry (Paraffin): 1:20-1:200. For formalin-fixed paraffin embedded tissues, staining is enhanced by boiling tissue sections in 10mM citrate buffer, pH 6.0, for 10-20 minutes followed by cooling at RT for 20 minutes prior to antibody incubation. Intensely stains the human neurofibrillary tangles, neuropil threads and neuritic plaques associated with Alzheimer’s disease. Observed to stain astrocytes.|Optimal dilutions to be determined by the researcher.||Recommended Positive Control:|Human T98G glioblastoma, SH-SY5Y cells or brain tissue.||Hybridoma:|Sp2/0-Ag14 myeloma cells with spleen cells from Balb/c mice.||Storage and Stability:|May be stored at 4°C for short-term only.
