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.    
To assess the linearity of the assay, samples were spiked with high concentrations of bovine cortisol in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.
  Sample Serum(n=4)

Please provide the following information regarding Bovine Cortisol ELISA Kit (CSB-E13064B):
1. What is the Uniprot/Accession number that this kit is designed for? Is the kit designed for XYZ species or is it designed for a different species such as Human and cross reacts with XYZ species?
2. Is the capture antibody a monoclonal or polyclonal?
3. What's is that standard? A recombinant protein or something else? If a recombinant protein, what is the host?
4. If recombinant protein, is it full length or partial?
5. What is the species of the standard– human or something else?
6. What sample type was tested with this kit (serum? plasma? Something else?) and what were the reference values.

Thanks for your inquiry.
Cortisol is small molecule and it is the same in all species, so there is no uniprot.
Since for different species, the matrix is different, we have developed kits for different species.
The standard is purified cortisol. This is a competitive kit. The plate is coated with specific antigen. The specific antibody is rabbit polyclonal antibody. The immunogen is modified by special modification.
HRP is conjugated with secondary antibody( goat anti-rabbit antibody).
Pls let me know if you have any further questions. Thank you.
