Hi Jodie,

I tried to squeeze this information out of the technical service of 
Pierce, but as usual, no information is available. However, the guy told 
me it is some kind of modified protein, so probably not  PVP-40.
In any case, I use 5% nonfat dry milk or BSA, and I will try their 
solution soon, to see if it is really better. Just email me if you want 
the result.
