High-performance liquid chromatography of insulin

Journal of Chromatography A, 1984
The elution behaviour of a selection of sequence variant and modified insulins has been compared on a C18 reversed-phase column. Observed elution times were compared with those expected from the nature of the differences from bovine insulin. In some cases prediction rules established for peptides are adequate to explain the observed elution and in ...

High-performance liquid chromatography of isopeptides

Journal of Chromatography A, 1986
High-performance liquid chromatographic (HPLC) methods are described for the structural analysis of clavicepamines, their analogues and branched-chain polypeptides, the analysis in synthetic stages of isopeptides (analysis of half-protected derivatives and purity control of active esters) and the differentiation between alpha- and iso-peptides (such as
