Interleukin-1b is produced by activated macrophages, IL-1B stimulates thymocyte proliferation by inducing il-2 release, b-cell maturation and proliferation, and fibroblast growth factor activity. IL1B proteins are involved in the inflammatory response, being identified as endogenous pyrogens, and are reported to stimulate the release of prostaglandin and collagenase from synovial cells.
Interleukin-1b Porcine Recombinant produced in E.Coli is a non-glycosylated, Polypeptide chain containing 154 amino acids and having a molecular mass of 17690 Dalton.
The IL-1b is purified by proprietary chromatographic techniques.
