WebABSTRACT. A relatively simple and efficient chromatographic method utilizing deaminated chitin (Dech), rather than chitin, has been developed and is described … WebThis review focuses on the heparin affinity chromatography. Diverse recombinant proteins can be successfully purified by this method. While effective, it is disadvantageous that heparin is an animal-derived material. Animal-based components carry the risk of contamination. Therefore, they are liable to strict quality controls and the validation ...
