NfL has been shown to associate with traumatic brain injury, multiple sclerosis, frontotemporal dementia and other neurodegenerative diseases. The Simoa NF-light™ assay is a digital immunoassay for the quantitative determination of NfL in serum, plasma and CSF.
In serum, NfL levels in genetic FTD patients were more than 8 times higher than in controls and serum NfL levels showed a high correlation with CSF NfL levels. 11. Rojas et al. (2019, poster presentation at AAIC ) observed elevated plasma Nfl concentration levels (Quanterix SIMOA) in a cohort of 290 subjects from the LEFFTDS consortium,
Since then, SIMOA assays for tau and NfL have been 12 Apr 2016 Serum NfL levels were highly related between ECL assay and Simoa (r=0.86, p< 0.001), and this was less visible between ELISA-ECL assay The Simoa NF-light™ assay is a digital immunoassay for the quantitative determination of NfL in serum, plasma and CSF. The antibodies also cross react with murine, bovine, and macaque NfL epitopes, and the assay can be used for research with these species. The highly sensitive Quanterix Simoa™ platform is evaluated for NfL measurement in both CSF and blood. There is a need to link historical ELISA data that use bovine NfL to that of Simoa using a recombinant human (rhuman) NfL standard. Background: A growing body of evidence suggests that the plasma concentration of the neurofilament light chain (NfL) might be considered a plasma biomarker for the screening of neurodegeneration in Alzheimer's disease (AD). Serum NfL levels were highly related between ECL assay and Simoa (r=0.86, p<0.001), and this was less visible between ELISA-ECL assay (r=0.41, p=0.018) and ELISA-Simoa (r=0.43, p=0.013). Multiple sclerosis (MS) patients had significantly higher serum NfL levels than controls when measured with Simoa (p=0.001) but not with the other platforms. Various diseases causing neuronal damage have resulted in elevated CSF concentrations.
Tau, neurofilament light-chain (NFL), glial fibrillary acidic Antibodies from the NF-light™ ELISA are available as single items enabling blood measurement on supersensitive platforms such as MSD (Meso Scale Discovery) and Quanterix SIMOA.

For analysis of NfL concentrations, the samples were transported on dry ice to the Clinical Neurochemistry Laboratory, Sahlgrenska University Hospital. The analyses were performed using an in-house assay on the single molecule array platform (Simoa; Quanterix, Lexington, MA, USA), as previously described in detail . Clinical Vaildation of Nfl- for MS is a Key Beachhead 22 FTD ALS Alzheimers TBI MS STUDIES CONFIRM NFL CLINICAL UTILITY Disease activity monitoring Drug efficacy monitoring Relapse/seventy prognostic Majority of published data obtained with Simoa ML 2019-05-06 · Our Simoa technology helped researchers measure NfL accurately in blood for the first time, and it’s incredibly rewarding to see the continued impact of our technology on these and many other METHODS: Forty-seven inpatients with confirmed COVID-19 had blood samples drawn on admission for assessing serum biomarkers of CNS injury by Single molecule array (Simoa), NfL and GFAp. Concentrations of NfL and GFAp were analyzed in relation to symptoms, clinical signs, inflammatory biomarkers and clinical outcomes. Sammantaget är plasma NFL en känslig men icke sjukdoms-specifik markör för axonskada och axonal degeneration.
neurofilament light (NFL) kan mätas i blodprov med Simoa-teknik [37], och studier på alzheimer visar en ökad nivå av NFL i plasma samt en
The data were examined using Kruskall–Wallis test and Dunn's post-test as well as receiver The initial NfL assay developed for the SiMoA assay used a home-brew method developed by the Basel group (Kuhle et al., 2016a). They used monoclonal NfL antibodies developed by Umam Diagnostics (47:3 and 2:1, subsequently purchased by Quanterix) along with bovine NfL calibrators.
The Simoa NF-light™ assay is a digital immunoassay for the quantitative determination of NfL in serum, plasma and CSF. The antibodies also cross react with murine, bovine, and macaque NfL epitopes, and the assay can be used for research with these species.
Wieslab Diagnostic Services now offer NfL testing from serum, using Simoa, and from CSF. We also offer fast and accurate clinical testing for a wide range of other diagnostic markers.
Multiple sclerosis (MS) patients had significantly higher serum NfL levels than controls when measured with Simoa (p=0.001) but not with the other platforms. Various diseases causing neuronal damage have resulted in elevated CSF concentrations. We explored the value of an ultrasensitive single-molecule array (Simoa) serum NfL (sNfL) assay in multiple sclerosis (MS). The single molecule array (Simoa) assay technology is significantly more sensitive compared to conventional detection systems like ELISA or electrochemiluminescence immunoassays. Simoa allows reliable detection of NfL in individual serum samples. NFL was determined with Single Molecule Array (Simoa™) technology (detection threshold 1.95 pg/mL).

The main difference between Simoa and conventional immunoassays lies in the ability to trap single molecules in femtoliter-sized wells, allowing for a “digital” readout of each individual bead to determine if it is bound to the target analyte or not. Wieslab Diagnostic Services was the first diagnostic laboratory in Scandinavia to offer NFL testing in blood and serum using the Simoa Technology. Measurement of NfL levels is of interest in disease activity, treatment response and prognosis in patients with neurodegenerative diseases. 2019-05-06 · Our Simoa technology helped researchers measure NfL accurately in blood for the first time, and it’s incredibly rewarding to see the continued impact of our technology on these and many other 2020-04-29 · Learn more about Simoa Assay Services: Ultra-Sensitive Biomarker Testing .

NfL has been shown to associate with traumatic brain injury, multiple sclerosis, frontotemporal dementia and other neurodegenerative diseases. The Simoa NF-light™ assay is a digital immunoassay for the quantitative determination of NfL in serum, plasma and CSF.
Background: Neurofilament light (NfL) chain is an established cerebrospinal fluid (CSF) biomarker for neuroaxonal injury. The highly sensitive Quanterix Simoa™ platform is evaluated for NfL measurement in both CSF and blood. Methods: With a single molecule array method (Simoa, Quanterix), plasma NfL concentrations were measured in 99 subjects with AD at the stage of mild cognitive impairment (MCI-AD; n = 25) or at the stage of early dementia (ADD; n = 33), and in nondemented controls (n = 41); in all patients, the clinical diagnoses were in accordance with the results of the four core cerebrospinal fluid (CSF
We found Simoa to be more sensitive than ELISA or the ECL assay.
