tyrosine sulfation of proteins?

Hi there,
I am working with MALDI-MS analysis of extracellular proteins which
in many cases are sulfated. Does anyone have experience in studying this?
Should one use sulfatases for the desulfation to prove that they are
sulfated or what is the general approach?

Thanks for all input!
