IL1B Recombinant Human Protein, Invitrogen™ Sino Biological™

This recombinant protein was expressed from a DNA sequence encoding the mature form of human IL1B (NP_000567.1) (Ala 117-Ser 269)

Brand:  Invitrogen 10139HNAE50

Product Code. 15244725

Description

Interleukin 1, beta (IL1B), a recombinant human protein, is supplied as a lyophilized powder. It is suitable for use in protein studies such as protein structure analysis and protein-protein interactions. In general, recombinant proteins can also be used as immunogens, protein standards, and in other cell biology research applications.

• Activity: 1.Measured by its binding ability in a functional ELISA; a. Immobilized recombinant human IL1B at 2μg/mL (100μL/well) can bind recombinant human IL1R2 with a linear range of 6.25-400ng/mL; b. Immobilized human IL1B at 10μg/mL (100μL/well) can bind human IL1R1, the EC₅₀ of human IL1R1 is 0.48μg/mL; 2. Measured in a cell proliferation assay using D10.G4.1 mouse helper T cells, the ED₅₀ for this effect is typically 0.5-5pg/mL
• Formulation: Lyophilized in 140mM NaCl, 2.7mM KCl, 10mM Na₂HPO₄, 1.8mM KH₂PO₄, pH 7.4, 5% Mannitol, 5% Trehalose, 0.02% Tween 80
• Reconstitution: Dissolve the protein in sterile double distilled water to a concentration of 0.2mg/mL or lower; aliquot and use as soon as possible
