Used in biomedical research to detect and quantify specific proteins, antibodies, or antigens in biological samples such as serum, plasma, or cell culture supernatants. Commonly applied in studying immune responses, infectious diseases, hormone levels, and biomarker discovery. Widely used in academic labs, pharmaceutical development, and diagnostic research due to its high sensitivity and ability to process multiple samples simultaneously. Supports research in areas like vaccine development, cancer studies, and autoimmune disease analysis.
