Used in biomedical research to detect and quantify P-Factor (also known as properdin) in human biological samples such as serum, plasma, or cell culture supernatants. This ELISA kit enables researchers to study the role of P-Factor in the activation and regulation of the complement system, particularly the alternative pathway. It is commonly applied in immunology and inflammation studies, helping to investigate conditions like infectious diseases, autoimmune disorders, and immune complex-mediated diseases. The kit provides a reliable and sensitive method for monitoring P-Factor levels in clinical and experimental settings, supporting both diagnostic research and therapeutic development.
