[Histonet] Casein Question in IHC

I routinely use 0.5% casein in Tris buffer for all my antibody diluents
and washes. After adding the appropriate number of grams to the buffer,
I leave the solution stirring overnight with the aid of a stir plate and
stir bar. Although the solution continues to have a cloudy aspect the
following morning, all the casein has actually gone into solution.

I had a problem to resolve casein in either PBS or Water when using it
for blocking apecific binding. Does anyone have the same problem? Can I
use BSA instead or can I heat a bit to help it resolve? Thanks!
