Active GMP Recombinant Porcine IL1B Protein, His-Tagged

• Cat.No.: IL1B-01P
• Product Overview: GMP Recombinant Porcine IL1B Protein, His-Tagged was expressed in Escherichia coli cell-derived in an animal component free process under cGMP guidelines.

Specification

• Species: Porcine
• Source: E.coli
• Tag: His
• Description: Interleukin 1 beta (IL-1β) also known as leukocytic pyrogen, leukocytic endogenous mediator, mononuclear cell factor, lymphocyte activating factor and other names, is a cytokine protein that in humans is encoded by the IL1B gene. There are two genes for interleukin-1 (IL-1): IL-1 alpha and IL-1 beta (this gene). IL-1β precursor is cleaved by cytosolic caspase 1 (interleukin 1 beta convertase) to form mature IL-1β.
• Form: Lyophilized
• Bio-activity: Measure by its ability to induce D10.G4.1 cells proliferation. The ED50 for this effect is <3 ng/mL.
• AA Sequence: MANVQSMECKLQDKDHKSLVLAGPHMLKALHLLTGDLKREVVFCMSFVQGDDSNNKIPVTLGIKGKNLYLSCVMKDNTPTLQLEDIDPKRYPKRDMEKRFVFYKTEIKNRVEFESALYPNWYISTSQAEQKPVFLGNSKGRQDITDFTMEVLSP with polyhistidine tag at the C-terminus
• Endotoxin: <0.1 EU per 1 μg of the protein by the LAL method.
• Purity: >98% as determined by SDS-PAGE. Ni-NTA chromatography
• Notes: Please use within one month after protein reconstitution.
• Storage: Lyophilized protein should be stored at -20°C. Upon reconstitution, protein aliquots should be stored at -20°C or -80°C.
• Storage Buffer: The protein was lyophilized from a solution containing 1X PBS, pH 7.4.
• Reconstitution: It is recommended to reconstitute the lyophilized protein in sterile H2O to a concentration not less than 100 μg/mL and incubate the stock solution for at least 20 min to ensure sufficient re-dissolved.
