Procedure

An aqueous solution (Stock solution I) of phenol, m-cresol, glycerol and NaCl was prepared together with an aqueous solution (Stock solution II) of LysB29Nε-hexadecandioyl-γ-Glu desB30 human insulin. An aqueous solution (Stock solution III) of histidine was prepared and pH was adjusted to 7.4 using diluted HCl/NaOH. A fraction of Stock solution I was mixed with variable amounts of Stock solution III and a fraction of Stock solution II was added and pH was adjusted to about 7.5. An aqueous 10 mM zinc acetate solution was added in six equal portions, pH was adjusted to 7.4 using diluted HCl/NaOH and the solution was filtered through a 0.22 μm sterile filter.
