Figure Lengend Snippet: Recombinant expression of SEO and identification of superantigenic activity of SEO. (A) SDS-PAGE analysis of purified SEO. Lane 1, supernatants of Escherichia coli encoding glutathione S-transferase (GST)-SEO; Lane2, purified GST-SEO fusion protein; Lane3, purified SEO. (B) Secretion of IFN-γ in mouse spleen cells in response to stimulation with 0.01 to 10 μg/mL of SEO. Positive control cells were stimulated with SEA. Negative control cells were stimulated with BSA.
