GFAP Simoa Assay Kit

Quanterix

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…

NEUROLOGY 2-PLEX B (Nf-L, GFAP*)

Quanterix

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…
