we have some troubles with the Xpress System, delivered by
Invitrogen. The system is based on the expression of
fusion proteins containing an enterokinase cleavage site
for "easy identification of the recombinant proteins" (Invitrogen).
Unfortunately, neither the enterokinase nor the Anti-XpressI antibody
ar available yet (in Germanyy at least). Who can help?
By the way, does anybody know whether there exists an antibody
against polyhistidine (metal binding) domains?
