Used in biomedical research to quantify apolipoprotein E levels in biological samples such as serum, plasma, or cerebrospinal fluid. Widely applied in studies related to lipid metabolism, cardiovascular diseases, and neurodegenerative disorders like Alzheimer's disease. The kit enables researchers to assess Apo-E concentration with high sensitivity and specificity, supporting investigations into genetic risk factors, disease progression, and therapeutic responses. Commonly used in clinical labs and research institutions for immunoassay-based detection.
