Abstract
The invention relates to a method for solubilising and purifying recombinant proteins which are expressed in bacterial host cells and are deposited as insoluble aggregates (inclusion bodies). The purification is based on conversion of the inclusion bodies into soluble forms using organic denaturing reagents and using chromatographic methods. Inorganic, alkaline, salt-containing eluents are selected here which, after purification is complete, enable the recombinant proteins, after neutralisation, to be made available in a form which can be employed directly for medical use and is physiologically acceptable. The method is particularly suitable for purifying allergens and allergen fragments.
