描述

Recombinant Human Interleukin 1, beta (IL1B) is a bioactive protein intended for use in cell culture applications. IL-1 is involved in a number of biological processes including the stimulation of T-helper cells, promotion proliferation and synthesis of immunoglobulins, and the activation of fibroblasts and NK cells.

• High purity—no interference from other proteins or contaminants
• High biological activity—more results with less protein
• Proven compatibility—Gibco® proteins bioassayed with Gibco® media

High Purity Recombinant Bioactive Protein
Recombinant Human Interleukin 1, beta is one of our more than 250 available Gibco® recombinant proteins. To help ensure Gibco® growth factors are of the highest quality, each protein is analyzed for purity along with structural homogeneity to ensure a biologically active protein.

High Biological Activity
In-house activity testing of Gibco® Recombinant Proteins includes cell proliferation, cytotoxicity, chemotaxis, calcium flux, secondary cytokine up-regulation, induction of surface antigen expression, antiviral, and protease assays. Recombinant Human Interleukin 1, beta (IL1B) specific activity is determined by the dose dependent proliferation of murine D10S cells.

Proven Compatibility
Gibco® proteins are bioassayed with Gibco® media. Since 1962, Gibco® has been the consistent provider of high quality media, reagents, and sera for reliable cell culture.
