We use powdered Diastase and phosphate buffer from Rowley Biochemical.  It
works quite well, especially in light of the fact we do so many of them.
Just dissolve 0.1 g of Diastase in 100 ml of the buffer (pH 6.0).  Preheat
to 37 degrees C, and place in the solution for one hour.  Rinse, and proceed
with the PAS reaction.

The catalog numbers are:  Diastase E-340-1, and Phosphate buffer, pH 6.0

Good luck to you!
