pertussis vaccine antigen
Pertactin (PRN), or P69 protein, is a highly immunogenic virulence factor of Bordatella pertussis, a bacterium that causes pertussis (whooping cough). Specifically, it is an outer membrane protein that promotes adhesion to tracheal epithelial cells. PRN is purified from Bordetella pertussis and is used for the vaccine production as one of the important components of acellular pertussis vaccine.
