Abstract
PURPOSE: To collect an antitumor substance consisting of a high polymer from bacte rium bodies of Actinomycetes.
CONSTITUTION: Bacteria of Actinomycetes are cultuned in an ordinary medium, and bacterium bodies are dissolbed or crushed by a mechanical or chemical means, and then subjected to solid-liquid separation by centrifugation or filtration to remove the cell wall parts, and a liquid fraction is obtained. The fraction is then subjected to a suitable combination of dialysis, gel filtration, and salting-out, to collect a high polymer having a molecular weight ≥ 10,000. The types of Actinomycetes may be of any genuses. The high polymer has a very powerful antitumor activity and extremely low toxicity.
