Recombinant Human IL-1 beta Protein (RP00002)

Datasheet

Overview

Product nameRecombinant Human IL-1 beta Protein
Catalog No.RP00002
DescriptionRecombinant Human IL-1 beta Protein is produced by E. coli expression system. The target protein is expressed with sequence (Ala117-Ser269) of human IL-1 beta (Accession #NP_000567.1) fused with an initial Met at the N-terminus and a 6×His tag at the C-terminus.
Bio-ActivityMeasured in a cell proliferation assay using D10.G4.1 mouse helper T cells. The ED50 for this effect is <12 pg/mL. The specific activity of recombinant human IL-1 beta is approximately 1.4 x 105 IU/μg, which is calibrated against recombinant human IL-1 beta WHO International Standard.
Purity> 95% by SDS-PAGE.
Endotoxin< 0.1 EU/μg of the protein by LAL method.
FormulationLyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.
SpeciesHuman
Interleukin-1 beta (IL1 beta or IL1B) also known as catabolin, is a member of the interleukin 1 cytokine family.This cytokine is produced by activated macrophages as a proprotein, which is proteolytically processed to its active form by caspase 1 (CASP1/ICE). This cytokine is an important mediator of the inflammatory response, and is involved in a variety of cellular activities, including cell proliferation, differentiation, and apoptosis. The induction of cyclooxygenase-2 (PTGS2/COX2) by this cytokine in the central nervous system (CNS) is found to contribute to inflammatory pain hypersensitivity.
