Untangle tau

Study tau from every angle with a comprehensive array of research tools to provide new insights into tau pathology. From aggregation inhibitors to kits and antibodies, find everything you need to untangle tau, in one place.

​​​Figure 1:  Formation of neurofibrillary tangles (NFTs) by the tau protein in tauopathies such as Alzheimer’s disease. 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

Tau is found in soluble form in the normal brain but in AD, becomes aggregated and insoluble. Easily detect total tau with a BSA and azide-free antibody, an antibody panel, or an ELISA kit from the table below.


Recommended product


Total tau antibody

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


Tau antibody panel

Human Tau ELISA Kit


Note: Studying insoluble tau can be problematic, consider using detergents such as RIPA and Sarkosyl1.

Tau phosphorylation

Tau function is governed by phosphorylation, which becomes dysregulated during pathology, resulting in mislocalization, aggregation, and neuronal death. Effortlessly study all aspects of tau phosphorylation with antibodies against different post-translationally modified sites.

Tau aggregation inhibitors

The presence of aggregated tau corresponds with pathology in diseases such as Alzheimer’s. Effectively inhibit the formation of neurofibrillary tangles with a potent tau aggregation inhibitor.
