For Research Use Only!
Host
E Coli
Purity/Purification
>97%, as determined by SDS-PAGE and HPLC
Form/Format
Recombinant Interleukin-11 was lyophilized from a 0.2 um filtered PB solution in 2.5% glycine, pH 4.5.
Sequence

Sequence Length
199
Domain
four helix cytokine core
Host Note
Optimized DNA sequence encoding Human Interleukin-11 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
Native human IL-11, generated by the proteolytic removal of the signal peptide and propeptide, the molecule has a calculated molecular mass of approximately 19 kDa.

Recombinant IL-11 is a disulfide-linked monomer protein consisting of 180 amino acid residue subunits, and migrates as an approximately 19 kDa protein under non-reducing conditions 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.
Related Product Information for IL-11 recombinant protein
IL11 is secreted by bone marrow stromal cells (fibroblasts) and is produced also by a number of mesenchymal cells. The IL11 receptor (alpha chain) utilizes gp130 as its signal transducer, which is also a component of other cytokine receptors. The alpha chain of the IL-11 receptor has been identified independently as Etl2. IL11 promotes primary and secondary immune responses in vitro and in vivo and modulates antigen-specific antibody reactions. IL11 promotes the proliferation of IL6 dependent plasmacytoma cell lines in the presence of neutralizing IL6 antibodies. IL11 also stimulates the T-cell dependent development of IgG-secreting B-cells in spleen cell cultures. IL11 inhibits the differentiation of pre- adipocytes. It induces the synthesis of some acute phase proteins by hepatocytes.

NCBI Description

The protein encoded by this gene is a member of the gp130 family of cytokines. These cytokines drive the assembly of multisubunit receptor complexes, all of which contain at least one molecule of the transmembrane signaling receptor IL6ST (gp130). This cytokine is shown to stimulate the T-cell-dependent development of immunoglobulin-producing B cells. It is also found to support the proliferation of hematopoietic stem cells and megakaryocyte progenitor cells. Alternatively spliced transcript variants encoding distinct isoforms have been found for this gene. [provided by RefSeq, Jun 2012]

Product Notes

The IL-11 il11 (Catalog #AAA553023) is a Recombinant Protein produced from E Coli and is intended for research purposes only. The product is available for immediate purchase. The amino acid sequence is listed below: MNCVCRLVLV VLSLWPDTAV APGPPPGPPR VSPDPRAELD STVLLTRSLL ADTRQLAAQL RDKFPADGDH NLDSLPTLAM SAGALGALQL PGVLTRLRAD LLSYLRHVQW LRRAGGSSLK TLEPELGTLQ ARLDRLLRRL QLLMSRLALP QPPPDPPAPP LAPPSSAWGG IRAAHAILGG LHLTLDWAVR GLLLLKTRL. It is sometimes possible for the material contained within the vial of "Interleukin-11, Recombinant Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.
