Protocol Available protocols: Western Blotting Specificity / Sensitivity Cleaved-IL-1 beta (Asp116) (D3A3Z) Rabbit Monoclonal Antibody (Biotinylated) recognizes endogenous levels of mature IL-1β protein only when cleaved at Asp116. Species Reactivity: Human Source / Purification Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Asp116 of human IL-1β protein. Background Interleukin-1β (IL-1β), one of the major caspase-1 targets, is a multifunctional cytokine that is involved in a host of immune and proinflammatory responses (1). It is produced primarily by activated monocytes and macrophages. It signals through various adaptor proteins and kinases that lead to activation of numerous downstream targets (2-6). Human IL-1β is synthesized as a 31 kDa precursor. To gain activity, the precursor must be cleaved by caspase-1 between Asp116 and Ala117 to yield a 17 kDa mature form (7,8). Detection of the 17 kDa mature form of IL-1β is a good indicator of caspase-1 activity.
