p-Tau 217 (Simoa® ALZpath) Assay
Simoa® ALZpath p-Tau 217 Assay
For researchers in the field of neurology, detecting phosphorylated Tau 217 (p-Tau 217) in plasma or cerebrospinal fluid (CSF) is crucial in advancing studies from discovery to clinical applications. The Quanterix Simoa® ALZpath p-Tau 217 Assay offers an ultrasensitive, reliable solution to measure p-Tau 217 levels, providing insights into neurodegenerative diseases like Alzheimer’s.
p-Tau 217: A Key Biomarker in Alzheimer’s Disease
Threonine 217 is one of the critical phosphorylation sites in tau, making p-Tau 217 a significant biomarker for Alzheimer’s disease. Research shows that p-Tau 217 levels in cerebrospinal fluid (CSF) and blood are significantly elevated in patients with Alzheimer’s, even in the early stages, indicating its potential as a valuable diagnostic and prognostic tool. Furthermore, studies have shown that p-Tau 217 can help differentiate Alzheimer’s disease from other forms of dementia, such as Lewy body dementia and frontotemporal dementia.
Applications and Intended Use
The Quanterix Simoa® ALZpath p-Tau 217 assay is validated for use in discovery and diagnostic research applications. The Simoa® ALZpath p-Tau 217 assay targets the proline-rich region of the Tau protein, which is highly conserved amongst the tau isoforms.
- Research on Neurodegenerative Diseases: By measuring phosphorylated tau protein levels in the blood, researchers can gain insights into the role of p-Tau 217 in the disease process and develop new diagnostics and neuro-prognostics for these debilitating diseases.
- Drug Discovery: Identify and screen promising drug candidates for further development and testing.
- Biomarker Discovery and Validation: Researchers can use the Simoa® ALZpath p-Tau 217 assay to validate emerging biomarkers, providing researchers with a reliable and accurate tool for biomarker discovery workflows.
