Abstract

Abstract Metal-associated somatotropins are useful for prolonged parenteral release of such somatotropins, for example release from compositions in which the metal-associated somatotropin is present in a biocompatible oil in an amount of at least 10% by weight of the composition.

Dependent Claim 20 words
A somatotropin of Claim 1 chemically associated with from about 0.3% to about 2% zinc by weight of said somatotropin.
Claim 6
Dependent Claim 10 words
A somatotropin of Claim 4 which is a bovine somatotropin.
Claim 7
Dependent Claim 23 words
A process which comprises precipitating a somatotropin from aqueous solution by adding to said solution a water-soluble salt of a non-toxic polyvalent metal.
Claim 8
Dependent Claim 23 words
A process which comprises precipitating a somatotropin from aqueous solution by adding to said solution a water-soluble salt of a non-toxic polyvalent metal.
