Your colleague handed you a novel strain of coli that is purifying a protein with a 6xHisTag; they claim it is superior to the TOP10 cells you have been using. But even with a larger culture size, you discover that your protein yield—using the same Ni-NTA column—is quite low. You discover that the novel strain of Escherichia coli generates an unusually high quantity of dicarboxylic acids, a byproduct of the citric acid cycle that is recognized for its ability to function as an all-purpose metal chelator. What do you think the issue is with purifying IMAC protein with this new strain of E. coli?
