Protocols

Specificity / Sensitivity

IL-1β (D3H1Z) Rabbit mAb (Mouse Specific) recognizes endogenous levels of total mouse IL-1β protein. This antibody can detect 500 pg of mature recombinant mouse IL-1β.

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding His124 of mouse IL-1β protein.

Background

Interleukin-1β (IL-1β) is a proinflammatory cytokine produced predominantly by activated monocytes and epithelial cells (1). Precursor IL-1β is cleaved by caspase-1 and mature IL-1β is then secreted (1-3). Target cells include macrophages and many other cell types. Signaling by IL-1β involves IL-1β binding to IL-1 accessory protein (IL-1-AcP); the complex then binds to IL-1RI (1,2). Signaling occurs through activation of MAP kinase and NF-κB pathways (1,2). IL-1β also binds to IL-1RII, which lacks an intracellular signaling domain and thereby serves as a high affinity decoy receptor. IL-1β binding to IL-1RI is inhibited by the negative regulator, IL-1R antagonist (IL-1Ra). IL-1Ra binding to IL-1RI does not signal and serves to block IL-1β signaling. IL-1β plays critical roles in the acute phase response and sepsis (1-3).
