SPEAR UltraDetect Neurofilament light exceptional precision with F.A.S.T. automated workflow
20 Jan 2026This application note focuses on SPEAR technology and its enhanced protein detection sensitivity and specificity compared to conventional immunoassays for detecting Neurofilament light in sub-microliter samples of serum or plasma. Integrated with the Formulatrix F.A.S.T. system, the wash-free assay workflow is further streamlined, reducing hands-on time to under 20 minutes and achieving remarkable precision (mean CV of 3.1%).

BiomarkersBiomarkers are biological markers which can be measured and evaluated to indicate a biological state. The use of biomarkers in research and diagnosis can indicate a normal or disease state or drug response of cells / tissues. Biomarkers include genetic markers, cell surface markers such as antigens, antibodies or receptors and secreted molecules such as cytokines. An assay system is required for identification of biomarkers. :qPCRQuantitative PCR (qPCR) is a molecular biology technique used to amplify and measure the amount of a specific DNA or RNA target. It plays a crucial role in gene expression analysis, pathogen detection, and quantifying DNA or RNA in various applications. Real-time PCR provides precise, quantitative results and is widely used in research, diagnostics, and clinical studies.
