In chemistry, dialysis is the process of separating molecules in solution by the difference in their rates of diffusion through a semipermeable membrane, such as dialysis tubing. Dialysis is a common laboratory technique that operates on the same principle as medical dialysis. In the context of life science research, the most common application of dialysis is for the removal of unwanted small molecules such as salts, reducing agents, or dyes from larger macromolecul… WebProtein 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 ...

WebNov 10, 2024 · Affinity chromatography is a very useful technique for "polishing", or completing the protein purification process. Beads in the chromatography column are cross-linked to ligands that bind specifically to the target protein. The protein is then removed from the column by rinsing with a solution containing free ligands. WebRepligen today entered an agreement to acquire FlexBiosys Inc. of Branchburg, NJ.
