Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.
Detection of Mouse
Caspase-11/Caspase-4 by Western Blot. Western blot shows lysates of mouse splenocytes untreated (-) or treated (+) with LPS. PVDF membrane was probed with 1:1000 dilution of Rabbit Anti-Mouse Caspase-11/Caspase-4 Monoclonal Antibody (Catalog # MAB8648) followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog # HAF008). Specific bands were detected for Caspase-11/Caspase-4 at approximately 36, 44, and 46 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Mouse Caspase-11 (commonly referred as Caspase-4) is a member of the cysteine-aspartic acid protease family known as caspases that function in initiating apoptosis or activating proinflammitory cytokines. Mouse Caspase-11 is expressed as a 343 amino acid latent zymogen. The active caspase-11 is cleaved into two subunits, p20 (aa 81-266) and p10 (aa 286-373). Caspase-11 is one of several caspases associated with the inflammasome and plays an important role in the activation of proinflammatory cytokines. Caspase-11 is activated by an autocatalytic mechanism or by cleavage by Caspase-8 in response to ER stress or bacterial infection, and its expression and activation can be induced by exposure to LPS. The active enzyme can cleave and activate Caspase-1 which in turn activates IL-1 beta. Mouse Caspase-11 has a 59 and 89% homology to human and rat Caspase-4, respectively.
