Product Summary

The Quantikine Rat IL-4 Immunoassay is a 4.5 hour solid phase ELISA designed to measure rat IL-4 levels in cell culture supernates and serum. It contains E. coli-expressed recombinant rat IL-4 and antibodies raised against the recombinant factor. This immunoassay has been shown to quantitate the recombinant rat IL-4 accurately. Results obtained using natural rat IL-4 showed dose response curves that were parallel to the standard curves obtained using the recombinant Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for natural rat IL-4.

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

Background: IL-4

IL-4 (Interleukin-4) is a cytokine that is primarily expressed by Th2-biased CD4+ T cells, mast cells, basophils, and eosinophils. It promotes cell proliferation, survival, and immunoglobulin class switch to IgG4 and IgE in human B cells, acquisition of the Th2 phenotype by naïve CD4+ T cells, priming and chemotaxis of mast cells, eosinophils, and basophils, and the proliferation and activation of epithelial cells. IL-4 plays a dominant role in the development of allergic inflammation and asthma. The type I receptor for IL-4, which is expressed on hematopoietic cells, is a heterodimer of the ligand binding IL-4 R? and the common ? chain (a shared subunit of the receptors for IL-2, -7, -9, -15, and -21). The type II receptor on nonhematopoietic cells consists of IL-4 R? and IL-13 R?1. The type II receptor also transduces IL-13 mediated signals.

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. 50 µL Assay Diluent
  3.   Add 50 µL of Assay Diluent to each well.
    4. 50 µL Standard, Control, or Sample
  4.   Add 50 µL of Standard, Control, or sample to each well. Cover with a plate sealer, and incubate at room temperature for 2 hours.
  5.   Aspirate each well and wash, repeating the process 4 times for a total of 5 washes.
    6. 100 µL Conjugate
  6.   Add 100 µL of Conjugate to each well. Cover with a new plate sealer, and incubate at room temperature for 2 hours.
  7.   Aspirate and wash 5 times.
    8. 100 µL Substrate Solution
  8.   Add 100 µL Substrate Solution to each well. Incubate at room temperature for 30 minutes. PROTECT FROM LIGHT.
    9. 100 µL Stop Solution
  9.   Add 100 µL of Stop Solution to each well. Read at 450 nm within 30 minutes. Set wavelength correction to 540 nm or 570 nm.
