Interleukin-1 beta (rpIL-1β) is a proinflammatory cytokine produced in a variety of cells including monocytes, tissue macrophages, keratinocytes and other epithelial cells. IL-1α and IL-1β are structurally related polypeptides that share approximately 27% amino acid (aa) identity in porcine. While IL-1α and IL-1β are regulated independently, they bind to the same receptor and exert identical biological effects. IL-1β stimulates thymocyte proliferation by inducing il-2 release, b-cell maturation and proliferation, and fibroblast growth factor activity.Recombinant Porcine IL-1β produced in E.coli is a single non-glycosylated polypeptide chain containing 154 amino acids. A fully biologically active molecule, rpIL-1β has a molecular mass of 17.7 kDa analyzed by reducing SDS-PAGE and is obtained by chromatographic techniques at GenScript.
Lyophilized recombinant Porcine IL-1β, remains stable up to 6 months at -80°C from date of receipt. Upon reconstitution, Porcine IL-1β should be stable up to 1 week at 4°C or up to 3 months at -20°C.
