Used in research settings to quantitatively measure levels of Human Fusion Protein (FUS) in biological samples such as cell lysates, tissue extracts, or cerebrospinal fluid. The kit is primarily applied in neuroscience and oncology research, particularly in studies related to amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD), where FUS protein mislocalization and aggregation are implicated. It enables researchers to monitor FUS expression levels under various experimental conditions, assess the efficacy of therapeutic compounds targeting FUS pathology, and support biomarker validation efforts in neurodegenerative disease models.
