I agree with DK, there is plentiful of Sulfo-NHS-activated dyes and respective affinity-labels.
Yoram's initial propasal to use activated Biotin triggered on question. As biotin is supposed to enter cells by some (transporter - is there any? which?) mechanism, wouldn't one predominately label this mechanism instead of "all" surface proteins? I'm just curiuous...
