Mouse IL-2 ELISA Kit

For detection and measurement of mouse interleukin 2
概要
The Mouse Interleukin 2 (IL-2) ELISA Kit is designed for the quantitative detection and measurement of mouse IL-2 in biological fluids such as serum, plasma, and cell culture supernatants. IL-2 is primarily secreted by activated CD4+ and CD8+ T cells, but is also produced by B cells and dendritic cells in smaller amounts. IL-2 is a major regulator of T cell development, contributing to T cell growth and expansion, as well as the development of regulatory T cells.

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, 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: 10 - 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 4 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 93/566.
• Recovery: A mid-curve recovery of 106 - 114% 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 3.1% (CV). The inter-assay precision of this assay is 6.7% (CV).
