Cell and tissue proteins were extracted as previously described (19 (

anti-caspase-1,
anti-IL-1β,
anti-cleaved caspase-1, anti-cleaved IL-1β, Affinity Biosciences, Cincinnati, OH, USA;
anti-caspase-11 p20, Santa Cruz Biotechnology, Inc.Dallas, Texas, USA) at 4 °C overnight. The membranes were washed with 1% TBST before and after incubation with
goat anti-rabbit IgG secondary antibody (LI-COR Biotechnology, Lincoln, NE, USA) or
goat anti-mouse IgG secondary antibody (LI-COR Biotechnology, Lincoln, NE, USA) for 1 h at room temperature.
Odyssey CLx imaging system (LI-COR Biosciences, Lincoln, NE, USA) was used to analysis protein expression as previously described (19 (
