Detection of activated G proteins

Hi all,

I am trying to detect to which G protein a GPCR is coupled and want to
label the G-protein with radioactive GTP. Which type of label is the
best. I think the photolabel technique is the best but the photolabel
is not commercially available ? Any ideas or protocols are welcome.

Thanks Tom
