The NULISAqpcr AD 5-plex Assay provides absolute quantitation of established amyloid-β-tau-neurodegeneration (ATN) & neuroinflammatory (I) biomarkers in a single multiplexed assay.
This innovative panel enables simultaneous measurement of key Alzheimer’s disease (AD)–related biomarkers – including brain-derived phosphorylated tau 217 (BD-pTau217), amyloid-beta 42 (Aβ42), glial fibrillary acidic protein (GFAP), and neurofilament light chain (NfL) to comprehensively monitor amyloid and tau pathology, neurodegeneration, and inflammation. It also includes measurement of APOE4 to determine carrier status of this genetic variant, which is the strongest genetic risk factor for AD and amyloid related imaging abnormalities (ARIA).
Biomarkers in the NULISAqpcr AD 5-plex Assay
In a single blood sample and with one streamlined workflow, we can reliably detect low‑abundance biomarkers across pathways and processes that are most relevant in Alzheimer’s disease biology.
| Biomarker | Biological Relevance | Applications |
|---|---|---|
| APOE4 | The strongest known inherited genetic risk factor for late-onset AD and ARIA |
|
| BD-pTau217 | Elevated levels reflect the presence of tau tangles, which are a defining feature of Alzheimer’s disease pathology |
|
| Aβ42 | Reduced levels in blood associate with increased Aβ plaque in the brain, an early indicator of disease development |
|
| GFAP | Elevated levels indicate astroglial activation which can amplify neuroinflammatory processes in AD and related disorders |
|
| NfL | Released into the blood when neurons are damaged or are undergoing degeneration |
|
Together, these biomarkers provide a multidimensional view of amyloid and tau pathology, neuroinflammation, and neurodegeneration – allowing for integrated assessment of AD and dementia via a single assay.
Setting a new standard for precision
The NULISAqpcr™ platform combines single‑molecule sensitivity with exceptional specificity, enabling reliable detection of low‑abundance biomarkers like BD-pTau217 (originating from the CNS) with attomolar (fg/mL) sensitivity in plasma.
In fact, the assay shows high correlation with the NULISAseq CNS Disease Panel 120 in its ability to provide high sensitivity and specificity for disease group stratification, as well as high correlation with APOE4 genotyping.
