Used in immunological research to quantitatively measure Human H-Factor (also known as Factor H) levels in biological samples such as serum, plasma, or cell culture supernatants. This ELISA kit is particularly valuable in studies related to the complement system, helping researchers assess the role of Factor H in regulating complement activation and preventing autoimmune responses. It is commonly applied in investigations of diseases associated with complement dysregulation, including atypical hemolytic uremic syndrome (aHUS), age-related macular degeneration (AMD), and other inflammatory or autoimmune conditions. The kit enables high-throughput, sensitive, and specific detection, supporting both clinical research and drug development efforts targeting the complement pathway.
