Resumen de: ES3041857A1
Screening for the diagnosis of Alzheimer's disease based on the detection of β-amyloid by FRET in plasma. Alzheimer's disease (AD) is the leading cause of dementia worldwide. Therefore, the search for biomarkers and the development of methodologies that allow for its early detection constitute a health and economic challenge. The concentrations of beta-amyloid Aβ 40 and AβThe presence of 42 Aβ oligomers in the cerebrospinal fluid and blood of Alzheimer's patients constitutes a good prognostic biomarker. Currently, Aβ oligomers with abnormal conformation can be detected using an ELISA-type immunoassay, or early detection of Aβ oligomerization can be achieved using an infrared immunosensor. A method based on fluorescence energy transfer resonance is proposed, employing a FRET (fluorescence energy transfer) pair consisting of compound A with general formula I and compound B CRANAD-2.
