  • Method for preparing antigen effective for preventing anthrax infection
    Patent number: 8519108
    Abstract: The method of the present invention comprising successive column chromatography processes for the purification of an anthrax protective antigen can achieve an improved purity of the anthrax protective antigen product by effectively removing impurities (e.g., cellular residual proteins in the culture solution) without the loss of anthrax protective antigen. Therefore, the method of the present invention can be advantageously used for economically producing the anthrax protective antigen on a large scale.
