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

Paramagnetic beads (4 × 10 6; Quanterix Corporation, Lexington, MA) were buffer exchanged and The correlation between FW and NfL, and the improvement in both FW and NfL after 12 weeks of cART treatment further reinforces this conclusion. Single molecule array (Simoa) by Quanterix is a To evaluate this, we measured plasma NfL and GFAP levels in a cohort of male and female ALD patients using SiMoA assay. We compared the levels of patients to healthy controls, determined the association with clinical parameters of disease severity and evaluated changes over 2‐year follow‐up. We measured tau, neurofilament 1 (NFL), glial fibrillary acid protein (GFAP), and ubiquitin-carboxy-terminal hydrolase L1 (UCHL1) with a highly sensitive single-molecule array (SIMOA ® by Quanterix ®) with the manufacturer's Neurology 4-plex panel ®.

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. Suspected neuronal damage in the CNS or PNS. Method. SIMOA (single molecule array) C a n be tested in serum, EDTA-plasma or CSF. Response. The result is reported as ng/L. If urgent NfL-testing is required, please contact the laboratory at +46 40 53 76 60. 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 Simoa NF-light™ assay is a digital immunoassay for the quantitative determination of NfL in serum, plasma and CSF. Background: Neurofilament light (NfL) chain is an established cerebrospinal fluid (CSF) biomarker for neuroaxonal injury. The highly sensitive Quanterix Simoa™ platform is evaluated for NfL measurement in both CSF and blood.

Our results support the feasibility of quantifying NfL in serum; the results correlate with the more-established CSF NfL test.

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. Simoa® Protein Assay Services. 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. Objective: We present the results of plasma biomarker quantification in a cohort of spinocerebellar ataxia type-3 (SCA3) carriers using a Simoa assay. Background: Development of treatments for SCA3 will require the characterization of accessible and reliable biomarkers that could be used as outcome measures in clinical trials.
