Description Our bioactive Interleukin-1 beta (IL-1 beta) Mouse, E. coli Recombinant Protein is a non-glycosylated polypeptide chain that contains 153 amino acids and has a molecula r mass of 17500 Dalton. The IL-1 beta is purified by proprietary chromatographic techniques. Summary IL-1 beta is a potent pro-inflammatory cytokine. Initially discovered as the major endogenous pyrogen, induces prostaglandin synthesis, neutrophil influx and activation, T-cell activation and cytokine production, B-cell activation and antibody production, and fibroblast proliferation and collagen production. Promotes Th17 differentiation of T-cells. Synergizes with IL12/interleukin-12 to induce IFNG synthesis from T-helper 1 (Th1) cells.Plays a role in angiogenesis by inducing VEGF production synergistically with TNF and IL6.Involved in transduction of inflammation downstream of pyroptosis: its mature form is specifically released in the extracellular milieu by passing through the gasdermin-D (GSDMD) pore. Acts as a sensor of S. pyogenes infection in skin: cleaved and activated by pyogenes SpeB protease, leading to an inflammatory response that prevents bacterial growth during invasive skin infection.

Purity Greater than 95.0% as determined by SDS-PAGE. Biological Activity The activity as determined by the dose-dependent proliferation of mouse D10S cells is 0.9-1.3 pg/ml, corresponding to a Specific Activity of 1.1 x 106 Units/mg. Reconstitution It is recommended to reconstitute the lyophilized IL-1 beta in sterile 18MΩ-cm H2O not less than 100 µg/ml, which can then be further diluted to other aqueous solutions. Shipping At ambient temperature. Upon receipt, store the product at the temperature recommended below. Storage/Expiration Lyophilized IL-1 beta, although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution, IL-1 beta should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles. Usage This product is intended for Laboratory Research Use Only. Not for use in diagnostic or therapeutic procedures.
