Precision
Intra-assay Precision (Precision within an assay): CV%<8%      
Three samples of known concentration were tested twenty times on one plate to assess.  
Inter-assay Precision (Precision between assays): CV%<10%      
Three samples of known concentration were tested in twenty assays to assess.    
             
Linearity
To assess the linearity of the assay, samples were spiked with high concentrations of human IL-23 in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

 Q&A
Q:

I am interested in measuring cytokines in patients affected by autoimmune thyroid diseases. For instance, i found the kit
(Human Interleukin 23 (IL-23) ELISA Kit,Catalog Number. CSB-E08461h) of your company,
Can this kit be used for the same purpose in lab animals (mouse, rats), if so, we are also interested in measuring IL-21, IL-22, IL-17A, IL-17F, all relevant kits produced by the same company, can they also be used for the same intention in lab animals??

A:
Thanks for your inquiry. For these cytokines IL-23, IL-21, IL-22, IL-17A, IL-17F,detection of cross-species is not advised,as it will be affected by the characteristics of antibodies and the matrix difference.
Regarding your research in measuring cytokines in patients affected by autoimmune thyroid diseases,we suggest you use human kits.While regarding your early laboratory research on lab animals,we suggest you use the corresponding lab animals kits.

If you are interested to order any one of them,we will foward your request to local distributor.Well,could you advise which coutry are you from?Thank you very much!
Q:

I am interested in this kit. I would like to know which subunit of IL-23 can be detected by the kit.
Please provide a detailed information about kit’s components:
a. Capture antibody or capture antigen.
b. Detection antibody (if applicable).
c. Standard – if recombinant protein, please specify sequence (including species source and accession no. if available) and expression host.

A:
Thanks for your inquiry.
Interleukin-23 (IL-23) is a heterodimeric cytokine composed of an IL-12p40 subunit (that is shared with IL-12 ) and the IL-23p19 subunit.
CSB-E08461h
This kit detects IL23(it is compound).
Capture antibody is mouse monoclonal antibody and detection antibody is goat polyclonal antibody.
Standard is a dimer of recombinant proteins expressed by eukaryotic cells in vitro.
Q:

Thank you for your assistance.
Is the 293 protein you are referring the IL-23 p19 subunit?
Because you just mention the immunogen is 293 cell-derived recombinant protein. Please clarify, what is the 293 cell-derived protein specifically? For example, is it the IL-23 p19 subunit?
It is good to know, if the antibodies bind to the p40 unit or the p19 subunit?
Looking forward to receiving your feedback.

A:
Thanks for your further inquiry. There are 2 antibodies in the kit, so there are 2 immunogens. They are designed against the 2 subunits of the compound.
Sorry we can not disclose which antibody is specific to which protein.
