Product Summary
The Quantikine Human IL-4 Immunoassay is a 4.5 hour solid phase ELISA designed to measure IL-4 levels in cell culture supernates, serum, and plasma. It contains E. coli-expressed recombinant human IL-4 and antibodies raised against the recombinant factor. This immunoassay has been shown to quantitate the recombinant human IL-4 accurately. Results obtained using natural human 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 human 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

    Store the unopened product at 2 - 8 °C. Do not use past expiration date.
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.

FAQs

  1. Why is plasma a validated sample type for the Human IL-4 Quantikine® ELISA (Catalog # D4050), but not in the high sensitivity version (Catalog # HS400)?

    • The recovery and linearity obtained with plasma samples assayed with the high sensitivity kit HS400 show too much variability and did not meet our specifications, unlike the D4050 which shows reliable recovery and linearity data with plasma samples.
