Product Summary for Human IL-16 Quantikine ELISA Kit
The Quantikine Human IL-16 Immunoassay is a 4.5 hour solid phase ELISA designed to measure human IL-16 in cell culture supernates, serum, and plasma. It contains E. coli-expressed recombinant human IL-16 and antibodies raised against the recombinant factor. It has been shown to accurately quantitate recombinant human IL-16. Results obtained using natural IL-16 showed linear curves that were parallel to the standard curves obtained using the recombinant kit standards. These results indicate that this kit can be used to determine relative mass values for natural human IL-16.

Recovery for Human IL-16 Quantikine ELISA Kit
The recovery of human IL-16 spiked to three different levels throughout the range of the assay in various matrices was evaluated.
| Sample Type | Average % Recovery | Range % |
|---|---|---|
| Cell Culture Media (n=4) | 100 | 94-106 |
| EDTA Plasma (n=6) | 105 | 96-117 |
| Heparin Plasma (n=6) | 102 | 86-112 |
| Serum (n=6) | 103 | 94-113 |
Linearity
To assess the linearity of the assay, samples containing or spiked with high concentrations of IL-16 were diluted with the appropriate Calibrator Diluent to produce samples with values within the dynamic range of the assay.

Background: IL-16
Interleukin 16 (IL-16), also named lymphocyte chemoattractant factor (LCF), is a 14-17 kDa single chain non-glycosylated polypeptide that was originally identified as a CD8+ T cell-derived chemoattractant for CD4+ cells. The expression of IL-16 precursor mRNA has been detected in various tissues including spleen, thymus, lymph nodes, peripheral leukocytes, bone marrow and cerebellum. In addition to its chemotactic properties, IL-16 has also been shown to suppress HIV-1 replication in vitro.
