Used in neuroscience and lipid metabolism research to quantify levels of 24S-hydroxycholesterol, a key biomarker reflecting brain cholesterol turnover. The kit enables researchers to study neurodegenerative diseases such as Alzheimer's and Parkinson's by measuring CYP46 enzyme activity in tissue samples or cerebrospinal fluid. It supports investigation into cholesterol homeostasis in the central nervous system and helps evaluate potential therapeutic interventions targeting brain cholesterol pathways. Widely applied in preclinical studies and drug development for neurological disorders.
