Anti-Factor I Antibody [KT22]

The Anti-Factor I Antibody [KT22] from Antibodies.com is a mouse monoclonal reagent that specifically recognizes Complement Factor I (CFI), a serine protease of the complement regulatory pathway. The KT22 clone binds the human Factor I protein and is validated for ELISA-based quantification of complement activation and regulation. Supplied as 100 µg of liquid IgG2b antibody in unconjugated form, the product can be paired with anti-Factor I reagents for custom assay development. For handling, store refrigerated between uses and aliquot to limit freeze-thaw cycles; avoid prolonged exposure to elevated temperatures. The antibody is reactive with human Factor I with no significant cross-reactivity reported for rat or mouse Factor I, supporting its use as a human-specific detection reagent in complement and innate immunity research. For research use only.
