Web1 Since elution conditions are quite harsh, it is recommended to collect fractions into neutralization buffer (100 to 200 µL of 1 M Tris-HCl, pH 9.0 per ml of fraction), so that the final pH of the fractions will be approximately neutral or perform a rapid buffer exchange on a desalting column (see Buffer exchange and desalting, Appendix 1). WebInstructions are supplied with each column. Desalting and buffer exchange can take less than 5 min per sample with greater than 95% recovery for most proteins. Alternative 1: Manual desalting with HiTrap™ Desalting 5 mL using a syringe ... Use a desalting column to simultaneously remove phenol red (a low molecular weight molecule) and ...

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. Desalting columns are used with both proteins and nucleic acids. They provide a fast, simple way to purify these biomolecules away from salts and small molecules. Common uses of desalting columns include: 1. Removal of salts 2. Removal of low molecular weight molecules, for example cofactors, inhibitors, … See more Desalting columns use the principle of size exclusion chromatography, also called gel filtration chromatography.
