BSA Powder for Western Blot

I regularly use this BSA powder for my Western Blot experiment, and more specifically, during the blocking step, which allows the saturation of all non-specific antibody sites. It is very easy to prepare, by adding TBS and Tween. However, in my case, my antibody did not have very good specificity, so BSA powder did not work properly, and I had to switch to milk for the blocking step.
