[1] How Prednisolone May Affect Weight Loss on Wegovy Prednisolone can significantly counteract the weight loss effects of Wegovy through several physiological mechanisms
A method for isolating a peptide, the method including purification of a GLP-1 peptide from a mixture comprising said peptide and related impurities via a cation exchange chromatography process, the cation exchange chromatography process comprising the steps of:separating said GLP-1 peptide and said related impurities of said mixture by elution in a solution consisting essentially of an organic modifier, water, optionally a salt component, and optionally a buffer, with a linear or step gradient or isocratically in salt component and/or with a linear or step pH-gradient or at a constant pH-value, wherein the pH-gradient or pH-value should be in the range where said peptide has a positive local or overall net charge different from the local or overall positive net charge of said related impurities so as to remove said related impurities;and subsequently, if necessary, subjecting to analytical tests and/or further purification, and isolating said peptide in a conventional manner, wherein the ratio of organic modifier to water, on a weight percent basis, is from 1:99 to 99:1, such as 1:99 to 80:20, 20:80 to 80:20, 30:70 to 70:30, 35:50 to 50:35, or 40:50 to 50:40
Non-reducing versus reducing SDS-PAGE run in parallel, size-exclusion chromatography for aggregate state, peptide mapping under both conditions for pairing assignment, or a cell-based functional assay are what actually answer it
