Hello, does anybody have experience with HIS capture leaching and/or have any empirical data that they can share to show decreased leaching with increased HIS tag (i.e., 6X vs 8X vs 10X HIS) for the same protein? In my experience, I believe I have used say 6X vs 8X HIS capture to stabilize the capture, but I cannot be certain and I do not have immediate access to the same protein with various HIS tags. Thanks!
I have collected some papares for you. I think the first two or three are the most interesting for you.
