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. Neurofilament light chains (NfL) are unique to neuronal cells, are shed to the cerebrospinal fluid (CSF), and are detectable at low concentrations in peripheral blood. 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.

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. “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.” 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 Quanterix Simoa offers an NfL assay, currently for research use only , and Roche has also developed an assay to measure NfL that when combined with plasma Aβ42 and Aβ40 increases the sensitivity of amyloid plaque detection (using CSF Aβ42/Aβ40 as the gold standard) from 75% to 86% but decreases the specificity from 72% to 70% . 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). We compared SimoaTM and EllaTM immunoassays to assess serum neurofilament‐light chain levels in 203 multiple sclerosis patients from the OFSEP HD study. There was a strong correlation (ρ = 0.86, p < 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.

Multiplex antibody-based assays In a study by Mahboob et al, the Olink Oncology I panel was used to analyze plasma samples from patients with Duke's staged colorectal cancer (CRC) to identify 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. 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 EllaTM instrument overestimated values by 17%, but as the data 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. Plasma NFL levels were measured in duplicate using an NF-Light assay and transferred onto the Simoa platform with a home-brew kit.

Measurement of NfL levels is of interest in disease activity, treatment response and prognosis in patients with neurodegenerative diseases.

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. Antibodies from the NF-light™ ELISA are available as single items enabling blood measurement on supersensitive platforms such as MSD (Meso Scale Discovery) and Quanterix SIMOA.

Neurofilament light protein in CSF and blood is associated with

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).

Hrusovsky hosted a panel discussion highlighting more insights from the AD/PD Quanterix's proprietary Simoa™ technology (named for single molecule array) is based upon the isolation of individual immunocomplexes on paramagnetic beads u The initial NfL assay developed for the SiMoA assay used a home-brew method developed by the Basel group (Kuhle et al., 2016a).
