Process for renaturation of recombinant, disulfide containing proteins at high protein concentrations in the presence of amines

A method for renaturation of proteins comprising adding to a solution of denatured, chemically modified or reduced proteins a refolding buffer containing a primary, secondary or tertiary amine. Said method has been applied, for example, to interleukin-4 and bovine pancreatic trypsin inhibitor (BPTI)...

Zusammenfassung:A method for renaturation of proteins comprising adding to a solution of denatured, chemically modified or reduced proteins a refolding buffer containing a primary, secondary or tertiary amine. Said method has been applied, for example, to interleukin-4 and bovine pancreatic trypsin inhibitor (BPTI), which were previously (i) solubilized in the presence of guanidinium hydrochloride as chaotronic agent, and (ii) subjected to sulfitolysis.
