Abstract

Tannic acid precipitated hemolytic streptococcus toxin is stabilized in aqueous suspension by the formation of flocculent aluminium hydroxide produced by the addition thereto of aluminium salt solution and the subsequent adjustment of the pH to 6 - 7. Aluminium chloride and sulphate, and potassium, sodium and ammonium alums are specified salts.
