Product details:
Human IL-4 ELISA Kit ab215089 is a rapid single-wash 90-min Sandwich ELISA to measure Human IL-4 in cell culture supernatant, citrate plasma, EDTA plasma, heparin plasma, plasma, serum. This SimpleStep sensitivity is 1.08 pg/mL.
How the assay works
Human IL-4 SimpleStep ELISA
employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA
plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA
protocol summary in the image section for further details.
Assay Specificity
Our SimpleStep ELISA
kits use recombinant monoclonal antibodies rigorously validated to ensure the highest level of consistency and reproducibility, improved sensitivity and specificity and ease of scalability and security of supply.
Please refer to our protocol booklet for more details.

IL-4 is a 129 amino acids long secreted protein. IL-4 is a cytokine produced mostly by activated T lymphocytes, mast cells and basophils. It has variety of immune response modulating functions by acting on number of cell types. IL-4 participates in several B-cell activation processes. It is a co-stimulator of DNA-synthesis. It induces the expression of class II MHC molecules on resting B-cells. It enhances both secretion and cell surface expression of IgE and IgG1. It also regulates the expression of the low affinity Fc receptor for IgE (CD23) on both lymphocytes and monocytes. IL-4 positively regulates IL31RA expression in macrophages.
