- Buffers are mixtures of a weak acid and a weak base that combine with a strong acid or base to limit changes in pH. True O Falsearrow_forwardPart 2 You decide to try anion exchange chromatography (DEAE column). To do this, you first equilibrate your column with column buffer (0.1M NaCI, pH 7.5). You then apply your desalted AS-P (Ammonium sulfate pellet) sample to the column, and collect the flow through (FT). Next, you elute the column with increasing concentrations of NaCl, and collect fractions (#1-5). Finally, you perform a quantitative assay of each fraction for activity. Below are three possible (independent) outcomes of this experiment. Explain what each outcome tells you about the conditions of the experiment under the conditions you ran each column. Make sure to detail the reasons behind each outcome (You may assume that the AS-P fraction had activity before you loaded it). Age A B.
