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.

Results: With the commercial Simoa assay, Method: Serum NFL levels were detected using the Single Molecule Array ( Simoa) technology in 30 ALS patients and 20 healthy controls (HCs). Results: There NFL concentrations were analysed and compared in 165 CSF and 225 plasma samples measured by SIMOA method at two different laboratory facilities (sites), 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 Archives. Neurofilament Light Chain (NfL), Serum. March 30, 2021 4:10 am Published by. Search. Search for: 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 8 Jun 2020 Ataxic SCA3 subjects showed increased levels of both NfL and pNfH.

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. The single molecule array (Simoa) assay technology is significantly more sensitive compared to conventional detection systems like ELISA or electrochemiluminescence immunoassays.

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).

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).

Method: Serum NFL levels were detected using the Single Molecule Array (Simoa) technology in 30 ALS patients and 20 healthy controls (HCs). Results: There were significantly elevated levels of serum NFL in patients with ALS than in the HCs (P < 0.001).

2019. NFL predicts clinical progression in pre-symptomatic Alzheimer’s disease 16 years before onset. 31 Jan 2019. NFL clinically validated for monitoring MS & treatment response in 2 Phase III trials.

Plasma NFL was significantly increased in the AD group, compared 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. 2019-05-06 Simoa Sees Health to Disease Continuum sickness begins symptoms SICK CARE Quanterix The Science of Precision Health neuro Current detection limit 10 biomarker NFL 20 .
