invitrogen nupage tris acetate gel recipe?

[Carsten Hoege]

Hallo,

I am using Invitrogens tris acetate PAGE gels for separation of large  
proteins, and they work fine. However, since we want to pour them in  
concentration that are not available, I was wondering, whether anyone  
knows the recipe of the gels. I checked files of the nupage patents  
for it but could only find nupage bis/tris gels.

best,
Carsten
