Elution conditions can either be changed in a linear gradient fashion or in a stepwise fashion. Often, a gradient elution protocol, in which the composition of the mobile phase changes linearly over time, is chosen to determine the elution profile and the elution buffer concentration at which the protein of interest is freed from the resin. Once this concentration has been determined, to save ...
