Matched CSF, serum and plasma samples from 112 multiple sclerosis patients were analyzed using both calibrators. 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 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. 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.

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).

NfL values generated from the assay also demonstrated association 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. Quanterix’ Simoa Technology Accelerates Critical Plasma Biomarker Research Presented at the 15th International several presentations demonstrated the role of blood based biomarkers, such as NfL, as secondary endpoints in ongoing Alzheimer’s drug trials.

Various diseases causing neuronal damage have resulted in elevated CSF concentrations. Ready-to-use Simoa® kits contain all the reagents necessary to run your assay on the HD-1, HD-X , SR-X or SP-X platforms. Elevated CSF and blood concentrations of neurofilament light chain (NfL) were found to correlate with an increase in the number of relapses, disability worsening, MRI disease activity, and brain volume loss in MS. 3, –, 9 A highly sensitive single molecule array (SIMOA) immunoassay has recently been developed to measure NfL in blood. 6,10 Method: Serum NFL levels were detected using the Single Molecule Array (Simoa) technology in 30 ALS patients and 20 healthy controls (HCs). Results: There was a significant elevated levels of serum NFL in patients with ALS than in the HCs (P < 0.001).

Until recently, these biomarkers could only be measured in CSF because the assays were not sensitive enough for detection of the much lower concentrations in plasma, but the introduction of the single‐molecule array (SiMoA) assay has enabled reliable quantification in blood samples as well.

increased serum NfL (sNfL) concentrations in clinically isolated syndrome (CIS) and MS patients.11,12,18,19 How-ever, these studies were limited by the still relatively low sensitivity of the assay.20 A novel single-molecule array (Simoa) assay has shown 126- and 25-fold higher sensi-tivity than the ELISA and ECL assays, respectively.20,21 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. Our results confirm and expand on previous studies 20, 21 showing that NfL can be reliably measured in serum using the Simoa technology, even at very low concentrations (down to a few pg/ml). The observed increase of NfL levels in serum with age seen in both HC and patient cohorts mirrors the age association described for CSF NfL levels, 38 and it is best explained by ongoing age‐related Quanterix announced that quantitative testing using its sNfL Assay and Simoa® technology can measure neuronal injury in COVID-19 patients' blood.

Based on a facility with two Quanterix Simoa® HD-1 Analyzers and our long-standing experience with this technology, we offer development, validation and screening of uniquely ultra-sensitive Simoa® biomarker assays, from pre-clinical samples, or, applying GCP standards, also from clinical samples. Single molecule array (SiMoA) is an ultrasensitive technology that can detect proteins in blood at sub-femtomolar concentrations (i.e., 10−16 M). In this review, we focus on the utility of SiMoA assays for the measurement of plasma or serum Aβ42, P-tau, T-tau, and NfL levels and discuss future directions. 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.
