Abstract

AT the suggestion of Dr. H. Jensen, of the Johns Hopkins University, Baltimore, an ultracentrifugal investigation of insulin has been carried out in my laboratory by Mr. B. Sjögren. A quantity of 0.25 gm. crystalline insulin was kindly put at my disposal by Dr. Jensen, and this small sample proved sufficient for a fairly complete study of the molecular weight and pH-stability region of insulin.
