![]() ![]() These additives are particularly suitable for situations where high protein concentration and long-term stability are required, including solution-state studies of isotopically labeled proteins by NMR. Specific protein-protein and protein-RNA interactions are not adversely affected by the presence of these amino acids. These amino acids are effective in preventing protein aggregation and precipitation, and they dramatically increase the long-term stability of the sample additionally, they protect protein samples from proteolytic degradation. Comparison of the ampholytes used in the rehydration buffer with respect to protein separation and resolution and focusing time. We demonstrate here that simultaneous addition of charged amino acids L-Arg and L-Glu at 50 mM to the buffer can dramatically increase the maximum achievable concentration of soluble protein (up to 8.7 times).

Q How does polyvalent buffers influence the protein binding capability of an AIEX column A Polyvalent buffers may compete strongly with proteins if ligands are of opposite charge to the buffer. Increasing a protein concentration in solution to the required level, without causing aggregation and precipitation is often a challenging but important task, especially in the field of structural biology as little as 20% of nonmembrane proteins have been found to be suitable candidates for structural studies predominantly due to poor protein solubility. A Imidazole is either uncharged or positively charged, so this buffer should be fine for anion exchange, just keep a low ionic strength during binding. ![]()
