Abstract

PURPOSE: To prepare an antitumor agent having high storage stability, by adding an inert protein to a suspension of cells of Streptococcus pyogenes having antitumor activity, and drying the suspension.
CONSTITUTION: An inert protein such as gelatin, albumin, γ-globulin, etc. is added to a suspension of cells of Streptococcus pyogenes having antitumor activity, and the suspension is dried to obtain an antitumor agnet. Streptococcus pyogenes, which is a variant of Streptococcus hemolyticus and capable of producing a hemolysin, streptolysin S, is extremely unstable even in a dried state. The addition of the above protein elongates the effective period of the agent to a practical length.
