DNA Affinity Chromatography, DNA affinity chromatography can be a low-tech method using gravity flow at 4°C, a disposable chromatography column, and DNA affinity resin prepared in the laboratory (see Preparation of a DNA Affinity Column). Include 10-20% glycerol and 0.025-0.1% NP-40 in the column buffers to suppress losses due to nonspecific adsorption of protein to surfaces. Load the protein in a buffer that is compatible with binding of the protein to its target site. Keith Brocklehurst et al
