DescriptionSMC® Human NF-L High Sensitivity Immunoassay Kit
OverviewThe SMC® Human NF-L High Sensitivity Immunoassay Kit contains all reagents required to perform the assay. This assay takes advantage of a standard immunoassay workflow configured in a standard plate format. Assay protocols are similar to existing sandwich ELISA methods with two key differences: 1) Elution buffer disrupts the sandwich, separating the labeled detection antibody for quantification. 2) The Erenna® and SMCxPRO® immunoassay systems detect analytes using Single Molecule Counting (SMC®) technology.
Background InformationThe SMC® Human NF-L High Sensitivity Immunoassay Kit utilizes Single Molecule Counting technology, based on the trusted sandwich immunoassay principle, to digitally measure Neurofilament Light Chain Protein (NF-L) in Human Serum, Plasma and Cerebrospinal Fluid (CSF) samples. A capture antibody specific for Human NF-L has been pre-coated onto paramagnetic microparticles (beads). The user pipettes beads, standards, and samples into uncoated microplate wells. During incubation, the NF-L present in the sample binds to the capture antibody on the coated beads. Unbound molecules are washed away during the subsequent wash steps. Fluor-labeled detection antibody is added to each well and incubated. This detection antibody recognizes and binds to NF-L that has been captured onto the beads, thus completing the immunosandwich. Elution buffer is then added and incubated. The elution buffer dissociates the bound protein sandwich from the beads surface releasing the labeled antibodies. These antibodies are separated during transfer to a 384-well read plate. The plate is loaded into the SMCxPRO® System where the labeled molecules are detected and counted. The number of fluor-labeled detection antibodies counted is directly proportional to the amount of NF-L present in the sample when captured. The amount of NF-L in unknown samples is interpolated from a standard curve.

Key Applications
  • Single Molecule Counting (SMC®)
Application NotesNeurofilament Light Chain (NF-L) is a low molecular weight member of a family of proteins involved in axonal development and function. NF-L accumulation is viewed as a telltale sign of axonal damage in the brain, and is a key marker in a wide range of neurodegenerative diseases, especially as a blood-based biomarker. We are proud to aid these efforts by offering the new SMC® Human NF-L High Sensitivity Immunoassay Kit. By coupling this assay with the powerful state-of-the-art SMCxPRO® detection system, researchers can accurately assess NF-L concentrations even in low abundance in human serum, plasma, and CSF samples, enabling studies that examine the relevance of this key analyte from health to disease.

This new streamline kit has the following features:

• Improved options for sample prep and incubation
• Lyophilization protein standard for uniform shipping and storage condition
• Increased reagent volumes to accommodate automation
• Rigorously developed to achieve accurate and reproducible performance on the state-of-the-art SMCxPRO® ultrasensitive immunoassay system
