Detecting tyrosine sulfation

[Jan Ulrik Thorup]

Hi! I am new to the field of protein chemistry, so I'd like some advice 
from you netters concerning the easiest method to detect whether a 
tyrosine in a small 8-meric peptide is sulfated or not.

If any of you have a good protocol reference, I'd be delighted to hear 
about it.
