Active Recombinant Rat Il1b Protein

• Cat.No.: Il1b-180I
• Product Overview: Recombinant Rat Il1b Protein without tag was expressed in HEK 293.

Specification

• Species: Rat
• Source: HEK293
• Description: Interleukin-1β is a proinflammatory cytokine produced in a variety of cells including monocytes, tissue macrophages, keratinocytes and other epithelial cells. Both IL-1 alpha and IL-1 beta 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-1 beta is a secreted cytokine, IL-1 alpha is predominantly a cell-associated cytokine.
• Form: Sterile Filtered White lyophilized (freeze-dried) powder.
