gelatin block for Westerns

[Helen McBride]

To get gelatin to go into solution, we would always heat a 1% solution
with stirring and when cooled added .01% Sodium Azide as a preservative
so we could store the solution at room temperature. We never had any
problems with it coming out of solution this way. The best block for
Immobilon that I have found is a combination solution of  1% gelatin with
2% dry milk.  Good Luck.
