I routinely add Tween 20 to my wash buffer but not BSA.  I do use 1% BSA in my
antibody dilution buffers but not Tween 20.  I have also noticed that
concentrations of Tween 20 noted in the literature varies from 0.05% to 1.0%, I
have always used 1.0% with no problems but I'm interseted in what others are
using and why.
