Used in neuroscience research to quantify neurofilament light chain levels in biological samples such as cerebrospinal fluid or blood. Helps assess neuronal damage or degeneration in experimental models, making it valuable in studies of neurodegenerative diseases like Alzheimer's, Parkinson's, and multiple sclerosis. Enables researchers to monitor disease progression, evaluate therapeutic efficacy, and explore mechanisms of neurotoxicity in mouse models. Widely applied in preclinical drug development and biomarker validation.
