Method for producing diagnostic anthrax allergen

Method provides recovery of a diagnostic anthrax allergen directly from a concentrated suspension of vegetative cells of a vaccine strain Bac. anthracis STI-1. The strain is grown on a nutrient medium based on a muriatic hydrolyzate of a fish flour by deep cultivation. The produced bacterial mass is washed in a separator to produce the concentrated suspension of vegetative cells. An allergenic protein fraction is recovered by alkaline hydrolysis, and the prepared hydrolyzate is fractioned. A protein allergen fraction is recovered from a supernatant of the recovered fraction by fractioning with an acetic acid solution; further the precipitation containing an end product is dissolved, dialyzed to produce a purified anthrax protein allergen. The preparation is presented in liquid and lyophilised forms.
