2020-07-29 · The ability to not only see but also accurately quantify NfL through an easily administered blood test using the ultra-sensitive Simoa platform was instrumental to the success of this project, and

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 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. 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 … Results/Methodology: The Simoa NF-light ® Advantage Kit was validated for CSF and qualified for serum and plasma, using both rhuman and bovine NfL calibrators. Matched CSF, serum and plasma samples from 112 multiple sclerosis patients were analyzed using both calibrators. 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).

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.

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.

If urgent NfL-testing is required, please contact the laboratory at +46 40 53 76 60. 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. 12-15 NfL and GFAP have been shown to serve as biomarkers of nerve tissue damage in a range of Simoa® Assay Kits 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. Our broad portfolio of available kits spans multiple therapeutic areas including cardiology, infectious disease, inflammation, neurology, and oncology. NFL was determined with Single Molecule Array (Simoa™) technology (detection threshold 1.95 pg/mL). Results: Mean NFL pg/mL (standard deviation ( SD)) was 341 (267) and 1475 (2358) in CSF and 8.2 (3.58) and 17.0 (16.94) in serum from controls and MS, respectively. In initial studies of blood NfL using ECL technology showed an association between serum NfL and brain atrophy over 2 years and number of MRI lesions, 64 though it had a poor prognostic value for patients with clinically isolated syndrome later converting to MS. 65 These studies on a small group of patients were limited by the sensitivity of the assay.
