Biological Activity:
The ED50 was determined by the dose - dependent stimulation of thymidine uptake by murine D10S cells is ≤ 1.0 pg/mL, corresponding to a specific activity of ≥ 1 x 109 units/mg.
Purity:
Greater than 98% by SDS-PAGE gel and HPLC analyses.

Endotoxin level is less than 0.1 ng per μg (1EU/μg).
physical-state:
Lyophilized
Storage Conditions:
The lyophilized IL-1 beta recombinant protein is stable for at least 2 years from date of receipt at -20°C. Reconstituted IL-1 beta is stable for at least 3 months when stored in working aliquots with a carrier protein at -20°C. As with any protein, exposing IL-1 beta recombinant protein to repeated freeze / thaw cycles is not recommended. When working with proteins care should be taken to keep recombinant protein at a cool and stable temperature.

Background:
IL-1β is a proinflammatory cytokine produced in a variety of cells including monocytes, tissue macrophages, keratinocytes and other epithelial cells. Both IL-1α and IL-1β binds to the same receptor and has similar if not identical biological properties. These cytokines have a broad range of activities including, stimulation of thymocyte proliferation, by inducing IL-2 release, B-cell maturation and proliferation, mitogenic FGF-like activity and the ability to stimulate the release of prostaglandin and collagenase from synovial cells. However, whereas IL-1β is a secreted cytokine, IL-1α is predominantly a cell-associated cytokine. Recombinant human IL-1β is a 17.3 kDa protein containing 153 amino acid residues.
