ANTIBODY PURIFICATION ON THE PROTEIN G COLUMN , buffer over the column after the pH 3 the first time to make sure no more is eluted There is no azide in the elution buffer because even 005% causes a significant absorbance (>01) at 280 at low pH It's very weird, but I also have the data to prove this Column run: 1 Clean the column with your elution buffer (30 - 50 ml) This is very .
Elution - Wikipedia Elution time and elution volume The "elution time" of a solute is the time between the start of the separation (the time at which the solute enters the column) and the time at which the solute elut In the same way, the elution volume is the volume of eluent required to cause elution Under standard conditions for a known mix of solutes in a .
Basic Guide to Chromatography - University of San Diego from one buffer to another (gradient elution) then you might consider using a wider short column But you should also be aware that the eluted sample will be more dilute and less resolution (separation from contaminants) If you are going to use a gradient elution or work with size exclusion resins, then you must have a taller thin column
