Immunohistochemical staining of human tissue using anti-IL-33 (human), mAb (IL33305B) (Prod. No. orb1272817) at 1:100 dilution. A. Immunoperoxidase staining (cytoplasmic) of formalin-fixed, paraffin-embedded human heart (100x, brown colour). B. Isotype control with IgG2a (negative control)

Inhibition of binding of recombinant human IL-33 (hIL-33) to human ST2 (hST2) in vitro using anti-IL-33 (human), mAb (IL33305B) (Prod. No. orb1272817). An indirect competitive ELISA was performed as follows; 1) coat microtiter plate wells with hST2-Fc (10 ug/ml) ; 2) add 2 ug/ml of IL-33 with or without a hIL-33 mAb to thewells followed by washing; 3) add anti-FLAG HRP conjugated (1:2000) to an enzyme; 4) after adding the TMB solution, incubate at RT in the dark for 20 minutes. Immediately read the plate at 450 nm

Immunoprecipitation of recombinant hIL-33 proteins using anti-IL-33 (human), mAb (IL33305B) (orb1272817). Recombinant hIL-33 Proteins were precipitated. The precipitated proteins were separated by SDS-PAGE, electroblotted, and visualized by Western blot/ECL reaction with anti-FLAG or anti-His.

Western blot analysis of human IL-33 using anti-IL-33 (human), mAb (IL33305B) (orb1272817) at 1:2000 dilution. 1. Recombinant human IL-33 (His tagged). 2. Recombinant human IL-33 (FLAG?-tagged). 3. Recombinant mouse IL-33 (FLAG?-tagged). 4. Other protein (His tagged, negative control).
