Tau is a microtubule-associated protein comprised of six human isoforms predominantly located in the axons of neurons. Neuronal and/or glial inclusions of tau can be detected in several neurodegenerative diseases or “tauopathies”, including Alzheimer’s disease (AD), frontotemporal lobar degeneration (FTLD), Pick’s disease, and cortico-basal degeneration (CBD) and Creutzfeldt-Jakob disease (CJD) may be characterized by their tau isoform profiles.
NEW Antibodies: Brain-derived Tau mAb 2B8 & p50 Tau mAb 15E3
CSF total Tau is a reliable Alzheimer’s disease-specific neurodegeneration marker. In contrast, plasma t-tau concentrations show large overlaps between diagnostic groups and do not correlate with CSF t-tau. Recent studies suggest, that plasma t-tau originates from peripheral, non-brain tissues. (Fernando Gonzalez-Ortiz, et al. Brain-derived tau: a novel blood-based biomarker for Alzheimer’s disease-type neurodegeneration, Brain, Volume 146, Issue 3, March 2023, Pages 1152–1165, https://doi.org/10.1093/brain/awac407)
To solve this problem, we offer our brand-new Anti-human TAU total mab 2B8 that selectively binds to continuous exon 4-5 sequences on brain-derived Tau isoforms, but not to peripheral „Big Tau“ isoforms containing the exon 4a insert.

Hyperphosphorylation of the neuronal tau protein is a hallmark of neurodegenerative tauopathies such as Alzheimer’s disease. New research suggests, that a few master phosphorylation sites - T50, T69, T111, T181, and T205 – trigger hyperphosphorylation of tau after they have been initially phosphorylated. (Stefanoska Ket al. Alzheimer's disease: Ablating single master site abolishes tau hyperphosphorylation. Sci Adv. 2022 Jul 8;8(27):eabl8809. doi: 10.1126/sciadv.abl8809)
Our antibody Anti-human phospho-50 TAU mab 15E3 specifically binds human TAU phosphorylated at amino acid position 50 (Thr) and has the potential to distinguish AD from control patients.
