| Product Name: | Mouse IL-9(Interleukin 9) ELISA Kit |
| Synonym: |
IL9, HP40, P40, TCGFIII, TCGF3, P40 T-cell and Mast Cell Growth Factor, P40 Cytokine, T-cell Growth Factor P40 |
| Background: |
This ELISA kit uses Sandwich-ELISA as the method. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Mouse IL-9. Standards or samples are added to the appropriate micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Mouse IL-9 and Avidin-Horseradish Peroxidase (HRP) conjugate are added to each micro plate well successively and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Mouse IL-9, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by adding Stop Solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentration of Mouse IL-9. The concentration of Mouse IL-9 in samples can be calculated by comparing the OD of the samples to the standard curve. |

Specificity
This kit recognizes some recombinant and natural Mouse IL-9. No significant cross-reactivity or interference was observed.
Typical data
For convenience in result calculation, absorbance can be used as ordinate and standard concentrations as abscissa. The standard curve provided in the manual is only for reference, and experimenters should draw the standard curve based on data of themselves.
Precision
Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high leve Mouse IL-9 were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Mouse IL-9 were tested on 3 different plates, 20 replicates in each plate.

Recovery
The recovery of Mouse IL-9 spiked to three different levels in samples throughout the range of the assay in various matrices was evaluated.
| Sample Type | Range (%) | Average Recovery (%) |
|---|---|---|
| Serum (n=5) | 89-104 | 95 |
| EDTA plasma (n=5) | 90-102 | 97 |
| Cell culture media (n=5) | 83-97 | 90 |
Linearity
Samples were spiked with high concentrations of Mouse IL-9 and diluted with Reference Standard & Sample Diluent to produce samples with values within the range of the assay.
