Abcam’s IL-4 (Interleukin-4) Human High Sensitivity in vitro ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative measurement of IL-4 in Human serum, plasma, buffered solution and cell culture media.
A monoclonal antibody specific for IL-4 has been coated onto the wells of the microtiter strips provided. Samples, including standards of known IL-4 concentrations, control specimens or unknowns are pipetted into these wells. During the first incubation, the standards or samples and a biotinylated monoclonal antibody specific for IL-4 are simultaneously incubated. After washing, the enzyme Streptavidin-HRP, that binds the biotinylated antibody is added, incubated and washed. A TMB substrate solution is added which acts on the bound enzyme to induce a colored reaction product. The intensity of this colored product is directly proportional to the concentration of IL-4 present in the samples.
This kit will recognize both endogenous and recombinant Human IL-4.

Standard curve of human IL-4, with background signal subtracted (duplicates; +/- SD).
IL-4 measured in cell culture supernatants from control (PBMC) or treated (PBMC+PHA; 2% PHA-M; LifeTechnologies) cells, grown for 48 hours (duplicates +/- SD). Samples tested neat - 1/10, control supernatant gave signals below level of detection.
