Does anyone know if the powdered egg white from Sigma (E0500) still contains active streptavidin? I would like to use it to block endogenous biotin instead of going through the hassle of obtaining fresh eggs, but I've read that avidin is inactivated by heat (pasteurization, in this case).
Also, if anyone already uses powdered egg white for this purpose, what concentration? Will 5% do?
