Properties of the Causative Agent of a Chicken Tumor : Iii. Attempts at Isolation of the Active Principle.

Abstract

By two methods a protein fraction can be separated out from a Chicken Tumor I extract, which carries all the tumor-producing agent. The precipitate can be dissolved and reprecipitated a number of times without loss of activity. The agent can be largely dissociated from the protein as shown by the fact that aluminum hydroxide will adsorb the protein from an… (More)
