WebDialyze against the Dialysis Buffer at 4 o C overnight (about 16 hrs). Dialysis is to remove imidazole or glutathione if Ni or glutathione column is used to remove the cleaved tag or TurboTEV Protease after cleavage. If desired, the target protein pool can be buffer exchanged first before TurboTEV cleavage. Removal of TurboTEV Protease WebHowever, we found that, when the final dialysis step was omitted and the protein left in IMAC column elution buffer (PBS containing imidazole), it remained soluble. Furthermore, several months old and precipitated protein could be redissolved in this buffer without loss of antigen binding. This observation and the largely pH-independent nature ...
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. ...
