    Product Description

    SignalStar multiplex immunohistochemistry (IHC) is an advanced technology for labeling multiple proteins simultaneously in tissue samples using specific primary antibodies and fluorescent detection reagents. This technology offers accuracy and reliability in visualizing and analyzing protein expression while maintaining spatial context and tissue architecture.

    SignalStar Oligo-Antibody Pairs are compatible with the SignalStar Multiplex IHC Buffer Kits for use in fluorescent multiplex imaging experiments. This product includes the oligo-conjugated antibodies and complementary oligos required for labeling your target protein on up to 10 slides. SignalStar Multiplex IHC Buffer Kits are required to amplify and image the target signal. Multiple oligo-antibody pairs can be conveniently combined into a multiplex panel using the SignalStar Multiplex IHC Panel Builder. SignalStar Multiplex IHC Kits & Reagents are not compatible with all of Cell Signaling Technology® products and protocols that are recommended for use in immunohistochemical assays.

    Protocol

    Specificity / Sensitivity

    Tau (GT-38) Mouse mAb (SignalStar™ Conjugate 0129) recognizes paired helical filament conformational tau protein. This antibody preferentially recognizes tau conformations related to Alzheimer's disease compared to other tauopathies.

    Species Reactivity:

    Human

    Source / Purification

    Monoclonal antibody is produced by immunizing animals with tau paired helical filaments from human Alzheimer's disease brain.

    Background

    Tau is a heterogeneous microtubule-associated protein that promotes and stabilizes microtubule assembly, especially in axons. Six isoforms with different amino-terminal inserts and different numbers of tandem repeats near the carboxy terminus have been identified, and tau is hyperphosphorylated at approximately 25 sites by Erk, glycogen synthase kinase-3 (GSK-3), and CDK5 (1,2). Phosphorylation decreases the ability of tau to bind to microtubules. Neurofibrillary tangles are a major hallmark of Alzheimer's disease (AD); these tangles are bundles of paired helical filaments (PHFs) composed of hyperphosphorylated tau. In particular, phosphorylation at Ser396 by GSK-3 or CDK5 destabilizes microtubules. Furthermore, research studies have shown that inclusions of tau are found in a number of other neurodegenerative diseases, collectively known as tauopathies (1,3).

    Alternative splicing of exon 10 results in the expression of two groups of tau: three-repeat and four-repeat tau. Isoforms 2, 4, and 5 express three microtubule binding repeat domains (Tau 3R) while isoforms 6, 7, and 8 express four microtubule binding repeat domains (Tau 4R) (4). Expression of Tau 3R and Tau 4R in cells can be different in mild or pathological conditions. For example, Tau 3R is preferentially expressed in Pick's disease (PiD) and corticobasal degeneration (CBD), while Tau 3R and Tau 4R are equally expressed in AD (5,6). The repeat-dependent tau has a different pattern of phosphorylation in different diseases, and also has the ability and patterns of aggregation (7-9). These varying patterns of aggregation result in disease specific conformational structures, including hyperphosphorylated straight filaments (SFs) and PHFs in AD compared to SFs and twisted filaments in both PiD and CBD (10,11).
