WebA gradient elution refers to a smooth transition of salt concentration (from low to high) in the elution buffer. Weakly binding proteins elute first, and stronger binding proteins elute last (i.e. they require higher salt concentrations in the buffer to compete them off the column) A gradient salt concentration can be made using a gradient maker. WebThe trend appeared to initially be to utilize CEX in a bind and elute mode as the first polishing step followed by AEX in a flow-through mode of operation. mAbs usually have a basic pI and hence bind tightly to CEX resins and tend to flow-through readily on AEX resins. The CEX step clears both HMW and HCP.
