has role protective antigen role protective antigen Burkholderia pseudomallei protein PotF Allen Xiang protein Oliver He PotF was evaluated as an antigen for a vaccine candidate against B. pseudomallei infection. Nonmembrane regions of the B. pseudomallei protein was expressed and purified from Escherichia coli and then evaluated as a vaccine candidate in an established mouse model of B. pseudomallei infection. When delivered with the monophosphoryl lipid A-trehalose dicorynomycolate adjuvant, the protein stimulated antigen-specific humoral and cellular immune responses. Immunization with the PotF protein domain afforded significant protection against a subsequent challenge with B. pseudomallei [PubMed: 17517877].
