概要

The Human Interleukin 13 (IL-13) ELISA Kit is designed for the quantitative detection and measurement of IL-13 in biological fluids such as serum, plasma, and cell culture supernatants. IL-13 is secreted by Th2 cells, mast cells and NK cells. IL-13 is involved in promoting B cell proliferation, induces class switching to IgG4 and IgE, recruits and activates IgE-producing B cells, and activates the JAK/STAT and IRS-1 and IRS-2 pathways.

The assay is based on the sandwich ELISA method, in which samples are added to ELISA strip plates pre-coated with capture antibodies specific for the cytokine. The captured cytokine is detected by addition of a biotinylated detection antibody, followed by streptavidin-horseradish peroxidase (SA-HRP), which binds the biotinylated antibody. Addition of the chromogenic enzyme substrate 3,3’,5,5’ tetramethylbenzidine (TMB) results in a colored product with an intensity directly proportional to the concentration of cytokine in the sample. The concentration of the cytokine is determined by comparison to a serial dilution of the cytokine standard analyzed in parallel.

Data

Representative Standard Curve

• Reportable Range: 3.2 - 1000 pg/mL. This is the concentration range in which measurement of the analyte can be done with the highest precision, accuracy, and linearity.
• Sensitivity: The limit of detection of this assay is 1 pg/mL. This is the analyte concentration with absorbance two standard deviations higher than the zero standard.
• Accuracy: The analyte standard of this ELISA was calibrated against NIBSC international standard 94/622.
• Recovery: A mid-curve recovery of 85 - 121% was determined by spiking defined amounts of analyte standard into serum or plasma samples in repeated experiments.
• Precision: The intra-assay precision of this assay is 3% (CV). The inter-assay precision of this assay is 14.9% (CV).
