“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 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.

11 The high sensitivity of the SIMOA 2020-02-10 · Serum NfL levels were determined by single molecule array (Simoa) assay using the capture monoclonal antibody (mAB) 47:3 (initial dilution 0.3 mg/mL; Art. No. 27016) and the biotinylated detector The SIMOA SR-X platform can deliver 1000-fold higher sensitivity than traditional ELISAs, yielding analyte detection in the femtomolar (fM) range and enabling analysis of previously difficult or even impossible-to-quantify biomarkers, such as CNS-specific or -derived biomarkers in serum and plasma as well as ultrasensitive PK assays for early dose escalation trials. 2018-08-08 · The Simoa assay may give researchers that ability, allowing them to quickly and efficiently measure NfL in the blood, transforming protein levels into a critical biomarker of precision health Simoa is based upon the isolation of individual immunocomplexes on paramagnetic beads using standard ELISA reagents. 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). Simoa® Assay Kits HD-X Analyzer™ SR-X™ Biomarker Detection System SP-X Imaging and Analysis System™ 2470 Arrayer Simoa® Accelerator Laboratory Uman NF-Light™ Homebrew – Custom Assay Development Using our ultra-sensitive Simoa technology, researchers measured plasma NfL concentration in 193 cognitively healthy controls, 197 patients with mild cognitive impairment (MCI), and 180 patients with AD dementia, and found that plasma NfL correlated with CSF NfL. 2019-05-16 · Ready-to-use Simoa NfL kits contain all the reagents necessary to run your assay on the HD-X, HD-1 or SR-X™ platform. Find out why more of the world's leading researchers are using ultra-sensitive Simoa NfL assays to drive studies forward in the areas of AD/PD, MS, and other neurological disorders, every day. “Using Simoa, researchers are now, for the first time, able to measure NfL in blood, vastly expanding the number and breadth of studies possible and providing insights into disease progression, patient response and drug performance, and accelerating drug development that was never possible before.” Learn more about Simoa Assay Services: Ultra-Sensitive Biomarker Testing .

The highly sensitive Quanterix Simoa™ platform is evaluated for NfL measurement in both CSF and blood. We found Simoa to be more sensitive than ELISA or the ECL assay. Our results support the feasibility of quantifying NfL in serum; the results correlate with the more-established CSF NfL test. The highly sensitive Simoa technology deserves further studies in larger patient cohorts to clarify whether … 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 Neurofilament light (NfL) Indication.

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 SR-X platform can deliver 1000-fold higher sensitivity than traditional ELISAs, yielding analyte detection in the femtomolar (fM) range and enabling analysis of previously difficult or even impossible-to-quantify biomarkers, such as CNS-specific or -derived biomarkers in serum and plasma as well as ultrasensitive PK assays for early dose escalation trials.

The performance of SIMOA ® NfL kit is under evaluation in a multicenter study. 35 Preliminary results showed an excellent performance in terms of intercenter variability. 35 The confirmation of these findings could lead to the worldwide implementation of NfL measurements in clinical chemistry laboratories.

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. Quanterix's proprietary Simoa™ technology (named for single molecule array) is based upon the isolation of individual immunocomplexes on paramagnetic beads u 2020-04-21 · Measurements of NfL concentration in blood serum using this technique correlate very well with those found in CSF, which allows patient NfL measurements to be taken from simple blood tests – a far less invasive and more accessible method. Wieslab Diagnostic Services now offer NfL testing from serum, using Simoa, and from 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.
