Abstract Given the lack of a serological test specific for Behget s disease its diagnosis rests upon clinical criteria.

We screened a cDNA library from human microvascular endothelial cells with serum IgG from two patients with Behget s disease and isolated a reactive clone specific to the carboxy-terminal subunit of Sip1 Sip1 C-ter . Using ELISA we measured IgG IgM and
