Recombinant anthrax protective antigen (PA, 83 kDa) was produced using a plasmid licensed from the NIH. The plasmid was introduced into a non-sporulating avirulent strain of Bacillus anthracis lacking both of the wild type plasmids, pX01 and pX02. Recombinant PA was purified using conventional chromatographic techniques. The resulting purified protein lacks all other anthrax virulence factors.

Each vial contains 0.93 mg of recombinant PA.
