=Expression of [His]6 constructs

Sample preparation

Frozen samples were thawed on ice and diluted to prepare a simple Coomassie-stain gel check. Is the overexpression visible? If so it might be too much for a physiologically relevant pulldown.

Sample setup

Heat samples for 2min at 85 deg C NOT at 95 deg C as we would usually do. This has to do with the composition of Invitrogen's reagents.
