Product Summary
The Quantikine Human CD40 Immunoassay is a 4.5 hour solid-phase ELISA designed to measure human CD40 in cell culture supernates, serum, plasma, saliva, urine, and human milk. It contains NS0-expressed recombinant human CD40 and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human CD40 showed linear curves that were parallel to the standard curves obtained using the Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for naturally occurring human CD40.

Precision
Intra-Assay Precision (Precision within an assay)
Three samples of known concentration were tested on one plate to assess intra-assay precision.
Inter-Assay Precision (Precision between assays)
Three samples of known concentration were tested in separate assays to assess inter-assay precision.

Recovery
The recovery of CD40 spiked to levels throughout the range of the assay in various matrices was evaluated.
| Sample Type | Average % Recovery | Range % |
| Cell Culture Media (n=4) | 105 | 95-115 |
| Serum (n=4) | 92 | 85-101 |
| EDTA Plasma (n=4) | 92 | 87-104 |
| Heparin Plasma (n=4) | 93 | 82-102 |

Linearity
To assess the linearity of the assay, samples containing and/or spiked with high concentrations of CD40 were serially diluted with Calibrator Diluent to produce samples with values within the dynamic range of the assay.
