Are you wanting an authentic standard or just a protein which
contains Fuc-Thr? Harris et al (Biochemistry 1991, vol. 30 pp.
2311-2314) use MS for identification of Fuc-Thr in tissue plasminogen
activator. But perhaps you already know this reference. Maybe
you'll have to get a friendly chemist to make Fuc-Thr for you!
