DEFINITION

Classification: 530/304

Metal complexes, e.g., zn-insulin, etc:

(under subclass 303) Peptides in which the peptide is a complex of insulin and a metal.

(1) Note. Typically the complex is formed by the addition of zinc chloride or a mixture of zinc chloride and protamine sulfate to insulin.

(2) Note. Examples: Neutral Protamine Hagedorn Insulin, Lente Insulin, Insulin Novo Lente, Depo-Insulin, Deposulin; Insulyl-Retard.
