Abstract
New methods for the refolding of recombinant granulocyte colony stimulating factor (G-CSF) from inclusion bodies are disclosed. The methods comprise two refolding steps. In particular, the methods comprise the solubilizing of G-CSF with a solubilizing agent, the oxidative refolding (first refolding step) of G-CSF in the presence of the solubilizing agent and an oxidizing agent, the efficient removal of the solubilizing agent, and a second refolding step to complete the folding of G-CSF in the absence of the solubilizing agent. Various methods are described for the efficient removal of the solubilizing agent from partially refolded G-CSF.
