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.
Catalog #T1029
ApplicationsSuitable for use in ELISA, Western Blot, Immunoprecipitation and Immunohistochemistry. Other applications not tested.
Recommended DilutionsImmunohistochemistry (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 ControlHuman T98G glioblastoma, SH-SY5Y cells or brain tissue.
HybridomaSp2/0-Ag14 myeloma cells with spleen cells from Balb/c mice.
Storage and StabilityMay be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 12 months after receipt. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
