NfL was assayed using Simoa. NfL levels across groups and tests were analyzed. Results: Difference in NfL was found between normal and impaired groups and was related to global cognition, processing speed, executive functions and a list of learning tasks with a significant negative effect for all diagnostic groups.

Blood NfL concentration was measured using an ultrasensitive single molecule array Simoa method, and the diagnostic accuracy to distinguish PD from APD

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.

Results: There was a significant elevated levels of serum NFL in patients with ALS than in the HCs (P < 0.001). 2018-07-28 · Simoa assay. For analysis of NfL concentrations, the samples were transported on dry ice to the Clinical Neurochemistry Laboratory, Sahlgrenska University Hospital. The analyses were performed using an in-house assay on the single molecule array platform (Simoa; Quanterix, Lexington, MA, USA), as previously described in detail .
