Abstract
Summary
A nucleoprotein-rich fraction has been obtained from alkaline blends of intestinal mucosa by placing the blend in the cold with or without adjustment of the pH to 11. After several days (or weeks, if the pH is not previously adjusted); a 2-phase liquid system becomes evident. The heavier, viscous, continually contracting phase, designated here as the tactoid, generally has a composition of approximately 50% nucleoprotein. 25% fat, and 25% ash. The nucleic acid is almost entirely of the desoxypentose type. The ash contains appreciable amounts of aluminum, the significance of which in the formation of the tactoid is unknown.
