PRODUCTION OF RED BLOOD COAGULANT FACTOR

摘要

PURPOSE:To provide a production of a new red blood coagulant originating from a marine plant where its coagulation activity is high and can be controlled by the ionic strength with excellent selectivity in saccharide chain recognition. CONSTITUTION:A red algae, Gracilaria sp., is extracted with a phosphate buffer solution and the extract is salted out to obtain a rough active fraction, then the fraction is subjected to chromatography to separate the fraction of more than 100,000 molecular weight whereby the objective coagulant factor is obtained.
