title: Determination of protamine peptides in insulin drug products using reversed phase high performance liquid chromatography.
abstract: This paper describes the establishment and validation of a reversed phase HPLC (RP-HPLC) method for determination of protamine peptides in protamine sulphate raw material and insulin drug products, discusses the analytical results obtained for a number of protracted insulin formulations and the potential of the method in connection with protamine sulphate raw material and final drug product quality control.
