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.
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.
Sterile Filtered White lyophilized (freeze-dried) powder.
The protein was lyophilized with no additives.
It is recommended to reconstitute the lyophilized Interleukin 1 beta in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Lyophilized Interleukin 1b althoµgh stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IL1b should be stored at 4°C between 2-7 days and for future use below -18°C.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles.
Amino Acid Sequence
The sequence of the first five N-terminal amino acids was determined and was found to be Met-Ala-Asn-Val-Gln.
Greater than 95.0% as determined by(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE.
The ED50 as determined by the dose-dependant stimulation of murine D10S cells is < 10 ng/ml corresponding to a Specific Activity of 100,000IU/mg.
