Used in biomedical research to quantify clusterin (apolipoprotein J) levels in biological samples such as serum, plasma, and cell culture supernatants. Enables study of apoptosis, inflammation, and neurodegenerative diseases like Alzheimer's. Supports cancer research by measuring clusterin expression linked to tumor progression and treatment resistance. Facilitates investigation of cardiovascular diseases and kidney injury due to clusterin's role in tissue protection and clearance of cellular debris. Provides a reliable, high-throughput method for protein detection in clinical and experimental settings.
