Hi, Since a surprisingly large number of people asked for the protocol, I compiled a quickie PDF document and posted it here:
http://www.xtals.org/pdfs/iodination.pdf Please excuse the inevitable consequences of haste - I am sure that the file is riddled with spelling errors and poor grammar. On the flip side, it also contains two sample images of electron density maps for mono- and bis- iodinated tyrosine (from the same crystal structure).
