The present invention refers to a method for binding a polycarboxylic acid to a solid phase. Further, the invention refers to a solid phase having a polycarboxylic acid immobilized thereto and methods of using the solid phase, e.g. for purifying His-tagged recombinant polypeptides.

Immobilisation of chelating groups for immobilised metal ion chromatography (IMAC)

The present invention belongs to the field of biotechnology. More specifically, the present invention provides a protease, a non-naturally occurring fusion protein comprising a corresponding protease recognition site, expression vectors encoding same, host cells comprising said expression vectors, kit of parts as well as methods applying the protease, fusion protein, and uses thereof, as defined in the claims. The presently disclosed protease/protease recognition site is particularly useful in methods requiring an orthogonal set of proteases, and is suitable for use in both prokaryotic and selected eukaryotic expression systems.
