How can I measure PKC activity in vivo or ex vivo in a manner that can be followed with a time course over hours?

I am looking for a way to measure PKC activity (esp. PKCalpha and/or PKCepsilon) in vivo or ex vivo (preferably in brain) in a manner that can be followed with a time course over hours. Any ideas?...
