the chromatographic ion exchange resin is chosen depending on the specific GLP-1 peptide to be purified and the conditions employed, such as pH, buffer, ionic strength etc., which are known to the person skilled in the art (that is, typically, pH below the isoelectric point (pl) of the GLP-1 peptide for cation exchange resins and pH above pl of the GLP-1 peptide for anion exchange resins, a sufficient buffer strength to maintain the desired pH, and a sufficiently low ionic strength possibly induced by the salt concentration), and includes but is not limited to Sepharose resins, Sephadex resins, Streamline resins, and Source resins from Amersham-Pharmacia Biotech, HyperD resins, Trisacryl resins, and Spherosil resins from BioSepra, TSKgel resin a solution consisting essentially of an organic modifier, water, optionally a salt component and optionally a buffer is intended to mean a solution containing one or more organic modifiers, water, one or more salt components or no salt component and one or more buffers or no buffer, and optionally one or more further conventional components which the person skilled in the art would consider adding, according to conventional ion exchange chromatography processes
