WebClogged column: Clean the column according to instructions. Make sure the sample has been centrifuged and/or filtered through a 0.45 µM filter before loading. Clogged system: clean system according to manual. GST-tagged protein is not eluted efficiently. The volume of elution buffer is insufficient. WebIn most cases, subsequent dialysis or desalting is required to exchange the purified protein from elution buffer into a more suitable buffer for storage or downstream analysis. The most widely used elution buffer for affinity purification based on protein interactions is 0.1 M glycine•HCl, pH 2.5-3.0.
