WebAffinity chromatography offers high selectivity, resolution, and capacity in most protein purification schemes. It has the advantage of utilizing a protein's biological structure or function for purification. As a result, purifications that would otherwise be time consuming and complicated, can often be easily achieved with affinity chromatography. Webrenaturation and purification of the r-protein. The most commonly used procedure for refolding of such denatured r-proteins is slow dialysis, or dilution into a buffer of near neutral pH (8). This results in significant dilution of the r-protein, typically to a few milligram of r-protein per milliliter of solution, with the formation of ...
