Product Code:RPES6229
Size:10µg
Species:Human
Expression Host:HEK293 Cells
Synonyms:SGRF, IL-23p19, CLMF p40, IL-12 subunit p40, NKSF2
Mol Mass:19.7&34.8 kDa
AP Mol Mass:19-21&40-60 kDa
Tag:C-6His
Purity:> 95 % as determined by reducing SDS-PAGE.
Endotoxin Level:< 1.0 EU per μg of the protein as determined by the LAL method.
Bio Activity:Measured by its ability to induce STAT reporter activity in 293F human embryonic kidney cells. The ED50 for this effect is 70-210 ng/ml.
Sequence:Arg20-Pro189&Ile23-Ser328
Accession:Q9NPF7&P29460
Storage:Generally, lyophilized proteins are stable for up to 12 months when stored at -20 to -80°C. Reconstituted protein solution can be stored at 4-8°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months.
Shipping:This product is provided as lyophilized powder which is shipped with ice packs.
Formulation:Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Please refer to the specific buffer information in the printed manual.
Reconstitution:Please refer to the printed manual for detailed information.
Background:Interleukin 23 (IL-23) is a heterodimeric cytokine composed of two disulfide-linked subunits, a p19 subunit that is unique to IL-23, and a p40 subunit that is shared with IL-12. The p19 subunit has homology to the p35 subunit of IL-12, as well as to other single chain cytokines such as IL-6 and IL-11. The p40 subunit is homologous to the extracellular domains of the hematopoietic cytokine receptors. Although p19 is expressed by activated macrophages, dendritic cells, T cells, and endothelial cells, only activated macrophages and dendritic cells express p40 concurrently to produce IL-23. IL-23 has biological activities that are similar to, but distinct from IL-12. Both IL-12 and IL-23 induce proliferation and IFN-gamma production by human T cells. While IL-12 acts on both naive and memory human T cells, the effects of IL-23 is restricted to memory T cells.
