Concentrations of NfL and GFAp were analyzed in relation to symptoms, clinical signs, inflammatory biomarkers and clinical outcomes.

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. 11.

The company is featuring the use of Simoa Technology, an ultra-sensitive technology for biomarker detection, in 36 studies, of which many focus on measuring the levels of NfL in the serum of MS We developed and validated a Simoa NfL assay using the capture monoclonal antibody (mAB) 47:3 and the biotinylated detector mAB 2:1 from UmanDiagnostics, 31 transferred onto the Simoa platform. mAB 47:3 was buffer exchanged and diluted to 0.3mg/ml. 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.

This shows that the PEA technology enables measure-ment with high sensitivity in a 92-plex format, matching the performance of the high-sensitivity single-plex "gold standard" assay, … Simoa unlocks insights from Neurofilament Light-chain (NfL), a previously obscure biomarker, for transforming neurology research and drug development Comparison of SimoaTM and EllaTM to assess serum neuroﬁlament-light chain in multiple sclerosis Audrey Gauthier1,a,Sebastien Viel2,3,a, Magali Perret2, Guillaume Brocard4,5,6,7, (NfL), Nf-medium and Nf-heavy chains.1 Upon neuro-axonal damage of the central nervous system Analysis of samples spiked with NfL antigen (N=10) and serum samples (N=122) from patients with MS demonstrated high correlation (R 2 =0.998/p 0.0001 and R 2 =0.838/p 0.0001, respectively) between NfL results derived from the automated analyzer and from the SIMOA Advantage kit. 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.

2016-01-01 · Plasma NFL levels were determined using the same monoclonal antibodies and calibrator as in the NF-light assay, transferred onto the Simoa platform using a homebrew kit (Quanterix, Lexington, MA, USA).

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. 11 The high sensitivity of the SIMOA 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 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. 2018-08-08 · The Simoa assay may give researchers that ability, allowing them to quickly and efficiently measure NfL in the blood, transforming protein levels into a critical biomarker of precision health 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. 2016-01-01 · Plasma NFL levels were determined using the same monoclonal antibodies and calibrator as in the NF-light assay, transferred onto the Simoa platform using a homebrew kit (Quanterix, Lexington, MA, USA).
