Description

IL-23 is a member of the IL-6 family of cytokines, and it is constituted by two subunits, p19 and p40. The p19-p40 heterodimer is stabilized by a disulfide bond. The subunit p40 is shared by IL-23 and IL-12 cytokines. p19 mRNA is expressed in endothelial cells and polarized T cells; nevertheless, p40 is not expressed by these cells. Therefore, the availability of functional IL-23 is limited by the expression of p40 and not p19. IL-23 exerts its biological activities through the interaction with a heterodimeric receptor complex composed of IL-12Rb1 and IL-23R. IL-23 activates Janus kinase (JAK)/signal transducer and activator of transcription signaling molecules (STAT). JAK2 is constitutively associated with the IL-23R chain, and binding of IL-23 to its receptor leads to phosphorylation of STAT1, STAT3, STAT4, and STAT5.

Source
The mouse IL-23 consists of two subunits linked via a disulphide bond: P19 (Accession# NM_031252: Met1-Ala 196) and P40 (Accession# NM_008352 : Met Met1-Ser 335). Mouse IL-23 was expressed in insect cells.
Molecular Mass
The total predicted molecular weight is 55.4 kD. The non-reduced protein migrates at approximately 60 kD and the DTT-reduced protein produces two bands at approximately 19 kD (Leu 20-Ala 196) and 40 kD (Met 23-Ser 335) by SDS-PAGE.

Distribution

IL-23 is highly expressed by activated dendritic cells, macrophages, and epidermal Langerhans cells.

Function
IL-23 promotes Th17 responses in vivo, and it is important for the survival and population expansion of Th17 cells. IL-23 induces proliferation of memory T cells and the induction of IL-17A and IL-17F in these cells. IL-23 induces the secretion of IL-17, IL-17F, IL-6, and TNFα in Th17 cells. In conjunction with IL-1, IL-23 is sufficient to induce naïve human T cells to produce IL-17A, IL-17F, IL-22, IL-26, IFN-γ CCL20/MIP-3α and the transcription factor RORγt. PGE2 favors the production of IL-23 and inhibit IL-12 in dendritic cells. PGE2 synergizes with IL-23 in expanding Th17 cells from purified memory CD4+ T cells activated in the absence of accessory cells. IL-23 induces IFN-γ production from T cells treated with PHA. In addition, IL-23 plays a key role in the pathogenesis of autoimmune and chronic inflammatory disorders. This role is supported by the identification of IL-23 receptor (IL-23R) susceptibility alleles associated with inflammatory bowel disease, psoriasis, and ankylosing spondylitis.

How does the activity of your recombinant proteins compare to competitors?

We quality control each and every lot of recombinant protein. Not only do we check its bioactivity, but we also compare it against other commercially available recombinant proteins. We make sure each recombinant protein’s activity is at least as good as or better than the competition’s. In order to provide you with the best possible product, we ensure that our testing process is rigorous and thorough. If you’re curious and eager to make the switch to BioLegend recombinants, contact your sales representative today!

What is the specific activity or ED50 of my recombinant protein?

The specific activity range of the protein is indicated on the product datasheets. Because the exact activity values on a per unit basis can largely fluctuate depending on a number of factors, including the nature of the assay, cell density, age of cells/passage number, culture media used, and end user technique, the specific activity is best defined as a range and we guarantee the specific activity of all our lots will be within the range indicated on the datasheet. Please note this only applies to recombinants labeled for use in bioassays. ELISA standard recombinant proteins are not recommended for bioassay usage as they are not tested for these applications.

Have your recombinants been tested for stability?

Our testing shows that the recombinant proteins are able to withstand room temperature for a week without losing activity. In addition the recombinant proteins were also found to withstand four cycles of freeze and thaw without losing activity.

Does specific activity of a recombinant protein vary between lots?

Specific activity will vary for each lot and for the type of experiment that is done to validate it, but all passed lots will have activity within the established ED50 range for the product and we guarantee that our products will have lot-to-lot consistency. Please conduct an experiment-specific validation to find the optimal ED50 for your system.

How do you convert activity as an ED50 in ng/ml to a specific activity in Units/mg?

Use formula Specific activity (Units/mg) = 10^6/ ED50 (ng/mL)
