功能
Levels were significantly higher in patients with biomarker-confirmed AD than in patients with non-AD dementia and unaffected controls, including in a cohort with postmortem confirmed diagnoses and in a memory clinic cohort with high disease heterogeneity. In this multicenter study, we examined the association of blood BD-tau with longitudinal cognitive changes and AD-characteristic brain atrophy rates along preclinical, MCI, and dementia stages of AD using four independent cohorts. We further assessed whether BD-tau concentrations increase with the co-occurrence of A+ and N+ abnormalities across the AD disease continuum and whether such A/N classification can be achieved using blood-based biomarkers to identify individuals at risk for cognitive decline and atrophy in the short term. In addition, we assessed the impact of genetic risk, comorbidities, and demographic factors, including ethnic self-identification, on plasma BD-tau concentrations and their clinical performance.

Elisa assay was performed by coating wells of a 96-well plate with 100 µl per well of capture antibody (HA723847) diluted in carbonate/bicarbonate buffer, at a concentration of 5ug/ml overnight at 4℃. Wells of the plate were washed, blocked with 150 µl 0.05% tween-20 1% BSA blocking buffer, and incubated with serial diluted Recombinant Brain-derived tau/BD-tau protein (HA210937) starting from 10000 pg/ml to 0 pg/ml and detect antibody (HA723848, Biotin, 0.2 µg/ml) for 1 hour at 30℃ with shaking. Then the plate was washed and incubated with 100 µl per well of SA-HRP for 0.5 hour at 30℃ with shaking. Detection was performed using an Ultra TMB Substrate for 10 minutes at room temperature in the dark.
