Product Summary for Human/Canine/Porcine Insulin Quantikine ELISA Kit
The Quantikine Human/Canine/Porcine Insulin Immunoassay is a 4.5 hour solid-phase ELISA designed to measure Insulin in cell culture supernates, serum, and plasma. It contains S. cerevisiae-expressed recombinant human Insulin and has been shown to accurately quantitate the recombinant factor. Results obtained using natural Insulin 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 Insulin.

Sample Values
Serum/Plasma - Samples from apparently healthy, fasting volunteers were evaluated for the
presence of human/canine/porcine Insulin in this assay. No medical histories were available for the
donors used in this study.

Cell Culture Supernates - Human peripheral blood mononuclear cells (PBL) were cultured in DMEM
supplemented with 5% fetal bovine serum, 50 μM beta-mercaptoethanol, 2 mM L-glutamine, 100 U/mL
penicillin, and 100 μg/mL streptomycin sulfate. Cells were cultured unstimulated or stimulated with
10 μg/mL PHA for 1 and 5 days. Aliquots of the cell culture supernates were removed and assayed
for human/canine/porcine Insulin. No detectable levels were observed.
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 twenty separate assays to assess inter-assay precision. Assays were performed by at least three technicians using two lots of components.

Recovery for Human/Canine/Porcine Insulin Quantikine ELISA Kit
The recovery of Insulin spiked to levels throughout the range of the assay in various matrices was evaluated
| Sample Type | Average % Recovery | Range % |
|---|---|---|
| Cell Culture Media (n=4) | 95 | 85-108 |
| EDTA Plasma (n=4) | 95 | 86-102 |
| Heparin Plasma (n=4) | 92 | 85-105 |
| Serum (n=4) | 96 | 87-103 |
Linearity
To assess the linearity of the assay, samples containing and/or spiked with high concentrations of Insulin were diluted with Calibrator Diluent to produce samples with values within the dynamic range of the assay.
