The method for the extraction of native surface protein antigen with a mol. wt. of 92 kD from vegetative cells of B.anthracis STI-1 and its purification was developed. The antigen was extracted with 3% sodium lauryl sarcosylate at 4 degrees C from bacterial mass previously treated with 0.1 M tris-HCl buffer solution, pH 8.0 Purification was carried out by(More)
A rapid method for producing a protective antigen (PA) and edema factor (EF), components of anthrax toxin, is described. The specific features of the method are as follows: addition of a mixture of protease inhibitors to the culture fluid; simultaneous concentration on a fiber filter and adsorption on hydroxylapatite, followed by non-linear gradient a(More)
