Topic: Brain proteins, microglia and lab models
Disease-specific oligomers Tau assay system is anticipated in Alzheimer disease (AD) to elucidate their etiological roles. We developed a highly sensitive and selective ELISA for high-molecular-weight oligomer tau (HMWoTau) with LLOQ of 0.3 pg/well for the first time, using a novel mouse monoclonal antibody APNmAb005. The target molecule was identified as HMWoTau with circa 2000 kD as a minimum size and the more oligomerized species (>5000 kD), in combination analysis with Size-Exclusion-Chromatography and Sucrose-Density-Gradient-Centrifugation for both recombinant human (rh) Tau-derived aggregates and AD brain-lysates in PBS(-).

Key findings
- We developed a highly sensitive and selective ELISA for high-molecular-weight oligomer tau (HMWoTau) with LLOQ of 0.3 pg/well for the first time, using a novel mouse monoclonal antibody APNmAb005.
- The target molecule was identified as HMWoTau with circa 2000 kD as a minimum size and the more oligomerized species (>5000 kD), in combination analysis with Size-Exclusion-Chromatography and Sucrose-Density-Gradient-Centrifugation for both recombinant human (rh) Tau-derived aggregates and AD brain-lysates in PBS(-).
- HMWoTau was labeled by Thioflavin S and visualized as a homogeneous globular particle (about 30 nm in diameter) by two different technologies of atomic force microscopy and dSTORM-Nanoimager.
- Specific quantitation was also confirmed by immune-absorption, rhHMWoTau-spiked, and cross-reactivity studies.
Why it matters
Researchers developed a new lab test that detects large clumps of tau protein in brain tissue and found these clumps increase with disease stage. This is laboratory work only and does not yet provide a treatment or cure.

How this study scored 40/100
Published in a peer-reviewed journal. Scored zero for study design, effect reported and randomised / blinded because the record does not state it. We have no data on senior author's track record and institution's track record, so those were left out: it earned 37 of the 93 points we could judge it on, which is 40 out of 100.
