Antisera to the C-peptide of human proinsulin were obtained by immunizing guinea pigs with synthetic benzyloxycarbonyl-C-peptide conjugated to human albumin with 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide. In three series of 10, the animals were

An improved synthesis of human C-peptide is described. Five fragments: 33-39, 40-46, 47-49, 50-54 and 55-63 were used in the total synthesis. In the fully protected C-peptide the N-terminal alpha-amino function was blocked by a benzyloxycarbonyl grou

Acylation of insulin with citraconic anhydride was studied at different pH values. The controlled acylation at pH 8.5 and 7 yielded mainly A1-citraconylinsulin (41%) and A1,B1-dicitraconylinsulin (39%), respectively. Acylation with excess reagent at

The semisynthesis of Arg-A-(SS)2 is described by the following chemical and enzymatic procedures: 1) A-(SSO theta 3)4 was acylated with arginine N-carboxyanhydride by the known method. Arg-A-(SSO theta 3)4 was purified, reduced and oxidized to Arg-A(
