Product Summary

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.


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

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


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.

Assay Procedure

Refer to the product for complete assay procedure.

Bring all reagents and samples to room temperature before use. It is recommended that all samples, standards, and controls be assayed in duplicate.
  1.   Prepare all reagents, standard dilutions, and samples as directed in the product insert.
  2.   Remove excess microplate strips from the plate frame, return them to the foil pouch containing the desiccant pack, and reseal.

  3. 100 µL Assay Diluent
  4.   Add 100 µL of Assay Diluent to each well.

  5. 100 µL Standard, Control, or Sample
  6.   Add 100 µL of Standard, control, or sample to each well. Cover with a plate sealer, and incubate at room temperature for 2 hours.
  7.   Aspirate each well and wash, repeating the process 3 times for a total of 4 washes.

  8. 200 µL Conjugate
  9.   Add 200 µL of Conjugate to each well. Cover with a new plate sealer, and incubate at room temperature for 2 hours.
  10.   Aspirate and wash 4 times.

  11. 200 µL Substrate Solution
  12.   Add 200 µL Substrate Solution to each well. Incubate at room temperature for 30 minutes. PROTECT FROM LIGHT.

  13. 50 µL Stop Solution
  14.   Add 50 µL of Stop Solution to each well. Read at 450 nm within 30 minutes. Set wavelength correction to 540 nm or 570 nm.
