2-D gels with phosphoproteins

Is there anyone who has already been successfull wit bi-dimensional gels
run on with 32P-labelled proteins ? If so, HOW ?

I am using the Pharmacia Biotech system with precast immobiline dry strip
gels for the first dimension and precast SDS polyacrylamide gradient gels
for the second dimension. I get very good results when I stain the gels
with silver. But if I run on phospho-labelled proteins (derived from
classical in vivo labelling protocols), I get a important background on
the autoradiography, making any analysis of the gel impossible.
Could you please indicate me how to decrease this background ?
Thanks for your attention.
