Effect of imidazole on the solubility of a his-tagged antibody
WebTo remove the imidazole, size exclusion chromatography (SEC) is an appropriate and potential technique. Moreover, imidazole concentration can be simply reduced from 1M to a reasonable level (0.02 – 0.2 M) including for crystallization reagents if the imidazole is inconsistent with the sample homogeneity. ... Dialysis is another good way to ... WebDetergent removal has traditionally utilized a variety of methods including dialysis, ion exchange chromatography, sucrose gradients, or acid or acetone precipitation. However, all these methods can be labor- and/or time-intensive, or detergent-specific.
