Recombinant Human IL-1β

Product Details

Catalogue Number: 200-01B
Description:

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 bind to the same receptor and have similar, if not identical, biological properties. These cytokines have a broad range of activities including the stimulation of thymocyte proliferation by inducing IL-2 release, B cell maturation and proliferation, mitogenic FGF-like activity, and 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.

Very Good
I purchased it as a proinflammatory stimulus for my experiment and it does work well.
