    摘要: The invention relates to a method for producing biologically active β-NGF from the proform proNGF. After expressing the proform of the β-NGF in a prokaryotic host cell, the recombinant protein is isolated in the form of insoluble inactive aggregates (inclusion bodies). After the solubilization thereof in a strong denaturing agent and the subsequent conversion thereof into the natural conformation, which is determined by the disulfide bridges present in the natural β-NGF, biologically active β-NGF is obtained by subsequently splitting-off the prosequence.

    摘要: The present invention relates to methods for obtaining a polypeptide in a monomeric form, the method comprising a) providing a solution containing the polypeptide in monomeric form and in aggregated form, wherein the ratio of monomeric to aggregated form is 4:1 or less, as determined by size exclusion chromatography, b) performing mixed-mode chromatography in bind-and-elute mode, or hydrophobic interaction chromatography in flow-through mode, or a size-exclusion chromatography, and c) performing a weak cation exchange chromatography in bind-and-elute mode or flow-through mode, and thereby obtaining the polypeptide in monomeric form.
