Protein Dialysis Kits

Protein dialysis often follows protein purification and chromatography procedures. This step allows for necessary buffer exchange or removal of salts or other contaminants to the protein samples. Dialysis is typically carried out using various forms of semi-permeable membranes and tubing. For smaller sample volumes and for convenience, ready-to-use dialysis cassettes centrifugal concentrator columns can also be used. The molecular weight cut off (MWCO) is a key factor for dialyzing protein samples. It is prudent to select a MWCO rating that is half the size of the target protein to retain. Other factors to consider include the sample volume range, and concentration factor.
