Neurofilament light (NF-L) is a 68 kDa cytoskeletal intermediate filament protein that is expressed in neurons. It associates with the 125 kDa Neurofilament medium(NF-M) and the 200 kDa Neurofilament heavy (NF-H) to form neurofilaments. They are major components of the neuronal cytoskeleton, and are believed to function primarily to provide structural support for the axon and to regulate axon diameter. Neurofilaments can be re…

Glial Fibrillary Acidic Protein (GFAP) is a class-III intermediate filament majorly expressed in astrocytic glial cells in the central nervous system. Astrocytes play a variety of key roles in supporting, guiding, nurturing, and signaling neuronal architecture and activity. Monomeric GFAP is about 55kD. It is capable of forming both homodimers and heterodimers; GFAP can polymerize with other type III proteins or with neurofila…
The Simoa Human Neurology 4-Plex E (N4PE) assay simultaneously measures four biomarkers in EDTA plasma and CSF. The targets are Abeta 40 (Aβ40), Abeta 42 (Aβ42), Glial Fibrillary Acidic Protein (GFAP™), and Neurofilament light (Nf-L). Each biomarker has been demonstrated to have significance for the investigation of neurodegeneration and brain injury, and to have utility for monitoring effectiveness of drug discovery and devel…
The Simoa Human Neurology 2-Plex assay (N2PB) measures two important neurology biomarkers in both cerebrospinal fluid (CSF) and blood. The two targets are neurofilament light (Nf-L) and glial fibrillary acidic protein (GFAP™), which have been studied as indicators of traumatic brain injury (TBI) severity. N2PB has been developed as a 2-Plex version of the Neurology 4-Plex B assay (N4PB). *Banyan GFAP™ is a registered tradem…
