Untangle Tau Proteins with a Comprehensive Range of Research Tools


An extensive range of research tools are available from Abcam to comprehensively study tau pathology. From aggregation inhibitors to antibodies and kits, customers can obtain everything they need to unravel tau, in one place.

Figure 1. Formation of neurofibrillary tangles (NFTs) by the tau protein in tauopathies such as Alzheimer’s disease (AD). Under pathological conditions tau becomes hyperphosphorylated and detaches from microtubules. Phosphorylated tau then aggregates to form paired helical filaments (PHFs) and neurofibrillary tangles (NFTs).

Total tau detection

In the normal brain, tau exists in soluble form. However, it aggregates and becomes insoluble in AD. Total tau can be easily detected with a BS and azide-free antibody, an ELISA kit, or an antibody panel from the table given below.


Recommended product


Total tau antibody

Anti-Tau antibody [TAU-5] - BSA and Azide free


Tau antibody panel

Tau Research Antibody Panel



Human Tau ELISA Kit


Note: Studying insoluble tau can be problematic, consider using detergents such as RIPA and Sarkosy1.

Tau phosphorylation

Phosphorylation, which governs tau function, becomes dysregulated during pathology, ending in mislocalization, aggregation, and neuronal death. All aspects of tau phosphorylation can be effortlessly studied with antibodies against different post-translationally modified sites.

Phosphorylation site

Recommended product


Serine 202 and threonine 205

Anti-Tau (phospho S202 + T205) antibody [EPR20390]


Threonine 231

Anti-Tau (phospho T231) antibody [EPR2488]


Serine 262

Anti-Tau (phospho S262) antibody


Serine 396

Anti-Tau (phospho S396) antibody [EPR2731]


Serine 422

Anti-Tau (phospho S422) antibody [EPR2866]


Customers who are in need of multiple phosphorylated tau antibodies can try Abcam’s tau antibody panel (ab226492).

Tau aggregation inhibitors

The presence of tau in aggregated form corresponds with pathology in diseases such as Alzheimer’s. The formation of neurofibrillary tangles can be effectively inhibited with a potent tau aggregation inhibitor.

Small molecule



TRx0237 mesylate (LMTX)

Reduces tau pathology and reverses behavioral impairment in mice2. Active in vitro and in vivo3.



Selective GSK-3 inhibitor (IC50 = 68 nM) of tau phosphorylation at the S396 site4.



ATP-competitive Dyrk1A inhibitor capable of reversing tau phosphorylation5.


GSK-3β Inhibitor VII

Cell-permeable, non-ATP competitive GSK-3β inhibitor (IC50 = 0.5 µM)6.


YM-01 (YM-1)

Allosteric Hsp70 modulator which potently reduces aberrant tau levels (EC50 ~ 0.9 μM)7.


Tau and neuroinflammation

In neurodegenerative disease, there is a complex interplay between misfolded proteins and neuroinflammation. Abcam offers a range of tools to investigate proinflammatory mediators, which allows researchers to study tau in the context of neuroinflammation.


Recommended product(s)


Mouse and human multiplex cytokine panels

Human Key cytokines (15 plex) Multiplex Immunoassay Kit


Mouse Key cytokines (14 plex) Multiplex Immunoassay Kit


TNF alpha ELISA kit

Mouse TNF alpha ELISA Kit


IL-1 beta ELISA kit
