WebAug 7, 2024 · The elution of the affibody was performed by grading the salt concentration (from 10 mM to1 M NaCl). Then the HEPES buffer pH 8.1 was exchanged to the conjugation buffer (25 mM phosphate, 150 mM NaCl, 0.5 mM EDTA pH 6.8) using a HiTrap Desalting, 1 × 5 mL column (GE Healthcare) prepacked with Sephadex G-25 Superfine.
WebColumn-based approaches for detergent exchange are often mild and efficient. A potential drawback with column-based methods is that the elution buffer may contain unwanted components that need to be removed from the eluted membrane protein. This problem can be solved by desalting and buffer exchange as described in the previous section. WebDesalting involves the chromatographic separation of macromolecules from smaller molecules such as buffer components, salts and unreacted labeling reagents. Buffer …
WebThese smaller molecules are subsequently flushed through the column with additional buffer volume. Our Dextran Desalting Columns are rigid for easy handling and provide excellent flow properties. Dextran is stable in water, salt solutions, organic solvents and alkaline or weakly acidic solutions. Dextran is also heat-stable and can be ...
