WebYou turn off the stopcock at the bottom of the column so that the eluent stops flowing. When you get back, you finish the column. You find that you didn't get very good separation between the compounds. What happened? a) Suppose you are working with a chromatography column that can hold about 20 mL of solvent. WebEluting Ig off the Dynabeads® Protein A is, in this example, performed by lowering pH using 0.1 M citrate (pH 2-3) as the elution buffer. The degree of acidity needed depends on the species and Ig sub-class, but at pH 3 most Ig will be eluted.
