The invention encompasses a process for purifying a peptide comprising loading a peptide onto a RP-HPLC column; washing the column with an aqueous solution of a pharmaceutically acceptable counterion salt; and eluting the peptide from the column with a solvent mixture of a organic solvent and an acid of the pharmaceutically acceptable counterion, wherein the aqueous solution has a pH of at least about 6.
这项发明涵盖了一种纯化肽的过程,包括将肽加载到RP-HPLC柱上;用药用可接受的对离子盐的
水溶液冲洗柱;并用含有有机溶剂和药用可接受的对离子的酸的溶剂混合物从柱中洗脱肽,其中
水溶液的pH至少约为6。
