背景说明: IL1B belongs to the IL-1 family. Interleukin 1 (IL-1) is a family of polypeptide cytokines consisting of two agonists, IL-1 alpha (IL-1F1) and IL-1 beta (IL-1F2) encoded by two distinct genes and perform identical biological functions. IL-1 stimulates thymocyte proliferation by inducing IL-2 release, B-cell maturation and proliferation, and fibroblast growth factor activity. IL-1 proteins are involved in the inflammatory response. It is identified as endogenous pyrogens, and is reported to stimulate the release of prostaglandin and collagenase from synovial cells.

英文别名: Interleukin-1 beta, Catabolin, IL1F2, IL1B.

描述:

Recombinant Human Interleukin-1 beta is produced by our E.coli expression system and the target gene encoding Ala117-Ser269 is expressed.

Accession: P01584

中文别名: Interleukin-1β蛋白; IL-1β蛋白

来源: Escherichia coli.

纯度: Greater than 95% as determined by reducing SDS-PAGE.

内毒素水平: Less than 0.1 ng/μg (1 IEU/μg) as determined by LAL test.

活性: Measured by its ability to induce NF-kB signaling in 293-IL1 Res cells. The ED50 for this effect is 20-100 pg/ml.Purity: Greater than 95% as determined by reducing SDS-PAGE. Less than 0.1 ng/ug (1 EU/ug) as determined by LAL test.

形态: Supplied as a 0.2 μm filtered solution of 20mM Tris-HCl, 150mM NaCl, pH 7.5.

溶解方法: Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 μg/ml. Dissolve the lyophilized protein in ddH2O. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.

储存/保存方法: Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 4-7°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months.
