This application discloses an invention comprising a polypeptide fraction isolated from commercial bacitracin and which contains most if not all of the anti-insulinase activity of bacitracin while exhibiting few if any of the antibacterial properties. The invention herein described also involves the use of this polypeptide fraction given orally. or if given parenterally either together (as composite) or in sequence as a means of treating diabetics. For such purposes, the insulin and anti-insulinase polypeptide fraction may be used as separate substances or chemically linked by ba wide variety of chemical linking agents well known in the art.
In addition to clinical uses, the application describes a method of using the polypeptide fraction as a growth promoter substance to be added to animal feed and also a composition useful for this purpose.
