Bordetella pertussis FHA
Filamentous haemagglutinin (FHA) is extracted from Bordetella pertussis and purified to a very high degree (>98%) with minimal degradation. A cell surface protein of Bordetella pertussis, FHA functions as an adhesin for this organism.
FHA is often used in combination with pertussis toxin for diagnostic screening purposes, whereas highly pure B. pertussis toxin alone is used predominantly for the monitoring of vaccination programmes
