1. A process for preparing an insulin analog-protamine crystal, which comprises:
- combining an aqueous solution of human insulin wherein Pro at position B28 is substituted with Asp, and Lys at position B29 is substituted with Lys or Pro in a hexamer association state, and a protamine solution at a temperature from about 5°
C. to about 22°
C.;
said aqueous solution comprising from about 0.35 to about 0.9% zinc by weight, human insulin wherein Pro at position B28 is substituted with Asp, and Lys at position B29 is substituted with Lys or Pro, and a phenolic derivative at a pH of about 7.1 to about 7.6;
said protamine solution comprising protamine at a pH of about 7.1 to about 7.6 such that the final concentration of protamine is about 0.27 to about 0.35 mg protamine to 100 IU of insulin analog.
