Used in biomedical research to detect and quantify AGR2 protein levels in cell lysates, tissue extracts, and biological fluids such as serum or urine. Widely applied in cancer studies, particularly in investigating gastrointestinal, breast, and lung cancers, where AGR2 is overexpressed. Helps researchers assess disease progression, evaluate therapeutic responses, and explore AGR2’s role in cellular stress, mucus production, and tumor microenvironment regulation. Commonly used in academic labs, pharmaceutical research, and clinical studies focused on biomarker discovery and validation.
