Host
E Coli
Purity/Purification
>97%, as determined by SDS-PAGE and HPLC
Form/Format
IL-1 beta was lyophilized from a 0.2 um filtered PBS pH 7.0.
Domain
heparin binding growth factor
Host Note
Optimized DNA sequence encoding Human Interleukin-1 beta mature chain was expressed in Escherichia Coli.
Endotoxin
Endotoxin content was assayed using a LAL gel clot method.
Endotoxin level was found to be less than 0.1 ng/ug (1EU/ug).
Reconstitution
A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers.
Molecular Weight Note
Mature Human IL-1 beta, is generated by the proteolytic removal of the signal peptide
and propeptide.The molecule has a calculated molecular mass of approximately 17 kDa.

Recombinant IL-1 beta is a disulfide-linked monomer protein consisting of two 154 amino acid residue subunits. Recombinant IL-1 beta migrates as an approximately 17 kDa protein under non-reducing and reducing conditions in SDS-PAGE.
Preparation and Storage
The lyophilized protein is stable for at least 2 years from date of receipt at -20 degree C.
Upon reconstitution, this cytokine can be stored in working aliquots at 2 degree - 8 degree C for one month, or at -20 degree C for six months, with a carrier protein without detectable loss of activity.

Avoid repeated freeze/thaw cycles.
Other Notes
Small volumes of IL-1 recombinant protein vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.
Related Product Information for
IL-1 recombinant protein
Monocytes are the main source of secreted IL1. They express predominantly IL1- beta while human keratinocytes express large amounts of IL1-alpha. Murine macrophages display a transition from IL1-beta to IL1-alpha production during maturation of monocytes into inflammatory macrophages.There are two functionally almost equivalent forms of IL1, IL1-alpha and IL1-beta that are encoded by two different genes. IL1-beta is the predominant form in humans while it is IL1-alpha in mice. Both forms of IL1 bind to the same receptor and therefore also show similar if not identical biological activities. The IL1-beta but not the IL1-alpha precursor must be processed before it can bind to the receptor. Both forms of IL1 bind to the same receptor and therefore also show similar if not identical biological activities. The receptor isolated from T-cells is expressed predominantly on T-cells and cells of mesenchymal origin. It binds both types of IL1 with equal affinity. This type is called also Type 1 receptor. It has been designated CD121a. The Type 2 receptor has been designated CD121b. It is isolated from B-cells, granulocytes, and macrophages. It is expressed predominantly on B-cells and cells of the myelomonocytic lineage and is encoded by a separate gene.

NCBI Summary for IL-1
The protein encoded by this gene is a member of the interleukin 1 cytokine family. This cytokine is produced by activated macrophages as a proprotein, which is proteolytically processed to its active form by caspase 1 (CASP1/ICE). This cytokine is an important mediator of the inflammatory response, and is involved in a variety of cellular activities, including cell proliferation, differentiation, and apoptosis. The induction of cyclooxygenase-2 (PTGS2/COX2) by this cytokine in the central nervous system (CNS) is found to contribute to inflammatory pain hypersensitivity. This gene and eight other interleukin 1 family genes form a cytokine gene cluster on chromosome 2. [provided by RefSeq, Jul 2008]
UniProt Comments for IL-1
IL1B: Produced by activated macrophages, 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, being identified as endogenous pyrogens, and are reported to stimulate the release of prostaglandin and collagenase from synovial cells. Monomer. Belongs to the IL-1 family.
