Used in biomedical research to quantify human β-cytocin (BTC) levels in biological samples such as serum, plasma, and cell culture supernatants. Enables investigation of BTC's role in cellular differentiation, tissue regeneration, and pancreatic development. Commonly applied in studies related to diabetes, stem cell research, and gastrointestinal diseases. Provides a sensitive and specific method for detecting low concentrations of BTC, supporting both clinical research and drug development.
