Binding of IL-33 (mouse) to ST2/IL-1RAcP is inhibited by IL-33 (mouse), mAb (rec.) (blocking) (Bondy-1-1) (preservative free). Methods: IL-33 (mouse) was coated on an ELISA plate at 1μg/ml. IL-33 (mouse), mAb (rec.) (blocking) (Bondy-1-1) (preservative free) or an unrelated mAb (recombinant) (Control) were added (starting at 40μg/ml with a twofold serial dilution) together with 100μl of supernatant of cells containing ST2 (human):Fc/IL-1RAcP (human):Fc. After incubation for 1h at RT, the binding was detected using an anti-Fc human antibody (HRP).
