protein phosphorylation

I would like to know whether someone could help me about the use of anti-phosphoserine antibodies.
I am using anti-phosphoserine kit from calbiochem (six differents monoclonal antibodies against different motifs containing pSer) but with little or not results.
I cannot use 32P labelling because I am studying radiation-induced protein phosphorylation.
I have high backgrounds on blots, despite I use BSA instead of NFDM, an poor results.
Could someone suggest me other antibodies or a well-working protocol?
Thanks a lot in advance
