Loaded Human IL-1R1, His Tag (Cat. IL1-HM1R1) on Anti-His-Biosensor can bind Human IL-1 alpha, No Tag with an affinity constant of 0.84 nM as determined in BLI assay.
Background
The interleukin (IL)-1 family of cytokines is currently comprised of 11 members that have pleiotropic functions in inflammation and cancer. IL-1α and IL-1β were the first members of the IL-1 family to be described, and both signal via the same receptor, IL-1R. Over the last decade, much progress has been made in our understanding of biogenesis of IL-1β and its functions in human diseases.
