Why is it Ammonium sulfate in my nested PCR mix?

Can you by a PCR buffer which contains Ammonium sulfate together with
Tris-HCL (pH 8.5), when the consentration is 4:1?

Or do I have to make these reagents by myself? 

I use primers that are degenerated and contains deoxyionisine, if that
can help.
