2018-07-28 · Simoa assay. 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 .

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

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). “GE and the NFL clearly recognize the pressing need to better understand and accurately diagnose mild traumatic brain injury, and we’re honored to be able to showcase how our Simoa technology is able to do just that,” said Kevin Hrusovsky, CEO and Executive Chairman, Quanterix.

NfL was assayed using Simoa. NfL levels across groups and tests were analyzed. Results: Difference in NfL was found between normal and impaired groups and was related to global cognition, processing speed, executive functions and a list of learning tasks with a significant negative effect for all diagnostic groups.

Suspected neuronal damage in the CNS or PNS. Method. SIMOA (single molecule array) C a n be tested in serum, EDTA-plasma or CSF. Response. The result is reported as ng/L. If urgent NfL-testing is required, please contact the laboratory at +46 40 53 76 60.

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. 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.

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,

The highly sensitive Quanterix Simoa™ platform is evaluated for NfL measurement in both CSF and blood.

Research and development of neurological tests including the Simoa N4PA assay is a result of two GE and NFL Head Health Challenge grants that have been awarded to Quanterix since 2015. About Quanterix. Quanterix is a company that’s digitizing biomarker analysis to advance the science of precision health.

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. NFL was determined with Single Molecule Array (Simoa™) technology (detection threshold 1.95 pg/mL).

Suspected neuronal damage in the CNS or PNS. Method.

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. 2016-01-01 · Plasma NFL levels were determined using the same monoclonal antibodies and calibrator as in the NF-light assay, transferred onto the Simoa platform using a homebrew kit (Quanterix, Lexington, MA, USA).
