Interleukin-1beta (IL-1ß) is a proinflammatory cytokine produced in response to inflammatory agents by a variety of cells, including monocytes, macrophages, and dendritic cells (DCs). IL-1ß and IL-1α are two distinct and independently regulated gene products that comprise IL-1 and signal through the Type 1 IL-1 receptor (IL-1R1).

IL-1α and IL-1β have nearly identical biological activity in that they induce adhesion molecule expression on epithelial cells, control fever induction, and play a role in arthritis and septic shock. Signaling activated by the IL-1R1 promotes these activities through a MYD88 signaling pathway similar to those associated with Toll receptors. Recombinant Human Interleukin-1-beta, produced in E.coli, is a non-glycosylated, polypeptide chain that contains 154 amino acids and has a molecular mass of 17.5 kDa. rHu IL-1ß is purified by proprietary chromotographic technique.
