Spin columns buffer exchange
Web2. After the spin is complete, check to ensure the retentate volume is at 50 µl or less in the concentrator body. If the volume is greater than 50 µl, spin the column several minutes longer until the volume is ≤ 50 µl. 3. Excess buffer will flow into the lower filtrate tube. Transfer the flow-through after each spin to a new ... WebThe same reservoir used to extend the processing volume during sample concentration can now be used for the diafiltration buffer.

WebPierce Polyacrylamide Spin Desalting Columns, 7K MWCO, are pre-packed with porous polyacrylamide beads and enable buffer-exchange and desalting of proteins and other macromolecular samples based on a molecular-weight cutoff (MWCO) of 7000 Da. WebBuffer exchange Protein solubility often depends on pH and/or ionic strength (salt concentration), and the exchange of buffer can therefore result in precipitation of the protein. Also, protein activity can be lost if the change of pH takes it outside of the range where the protein is active.
