How to make a-32P-GMP

[Friedemann Janus]

Hi,

I'm trying to crosslink a protein to GMP, but a-32P-GMP is not 
comercially available. Therefore I'm looking for a way to make GMP out of 
a-32P-GTP. I'm thinking about using phosphodiesterase. Has anybody done 
something similar ? Any tips ?
Thanks in advance

Friedemann
