Used in biomedical research to quantitatively measure S100 protein levels in rat tissue extracts, serum, or cerebrospinal fluid. This kit is particularly valuable in neuroscience studies, where S100B protein serves as a biomarker for astrocyte activation and blood-brain barrier integrity. It is widely applied in models of traumatic brain injury, stroke, neurodegenerative diseases, and neuroinflammation. The assay helps researchers assess neural damage, monitor disease progression, and evaluate therapeutic interventions. Due to its high sensitivity and specificity, the kit supports reliable detection of low-abundance S100 proteins, enabling accurate data collection in preclinical studies.
