Product Summary for Human Sonic Hedgehog/Shh N-Terminus Quantikine ELISA Kit
The Quantikine Human Sonic Hedgehog/Shh N-Terminus Immunoassay is a 4.5 hour solid-phase ELISA designed to measure human Shh-N in cell culture supernates, serum, and heparin plasma. It contains E. coli-expressed recombinant human Shh-N and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human Shh-N 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 Shh-N.

Precision
Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested twenty times on one plate to assess intra-assay precision.
Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in thirty separate assays to assess inter-assay precision. Assays were performed by at least three technicians using three lots of components.

Recovery for Human Sonic Hedgehog/Shh N-Terminus Quantikine ELISA Kit
The recovery of human Shh-N spiked to levels throughout the range of the assay in various matrices was evaluated. Samples were diluted prior to assay as directed in the Sample Preparation section.
| Sample Type | Average % Recovery | Range % |
|---|---|---|
| Cell Culture Media (n=4) | 108 | 100-117 |
| Heparin Plasma (n=4) | 97 | 85-117 |
| Serum (n=4) | 99 | 81-117 |
Linearity
To assess the linearity of the assay, samples containing high concentrations of human Shh-N were serially diluted with Calibrator Diluent to produce samples with values within the dynamic range of the assay. Samples were diluted prior to assay.
