ELISA Interleukin 2 (IL-2)

Reactivity:Chicken (Gallus) UniProt:N/A Abbreviation:IL-2 Alternative Names:IL-2; TCGF; lymphokine; T cell growth factor|aldesleukin|interleukin-2|involved in regµLation of T-cell clonal expansion Application:ELISA Range:15.6-1000 pg/mL Sensitivity:7 pg/mL Intra-AssayCV:?7.4% Inter-AssayCV:?9.6% Recovery:0.95 Sample Type:Serum, Plasma, Other biological fluids Detection Method:Sandwich Analysis Method??:Quantitive Test principle:This assay employs a two-site sandwich ELISA to quantitate IL-2 in samples. An antibody specific for IL-2 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyIL-2 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjµgated antibody specific for IL-2 is added to the wells. After washing, Streptavidin conjµgated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of IL-2 bound in the initial step. The color development is stopped and the intensity of the color is measured. Product Overview: Stability:The stability of ELISA kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition. The loss rate was determined by accelerated thermal degradation test. Keep the kit at 37°C for 4 and 7 days, and compare O.D.values of the kit kept at 37°C with that of at recommended temperature. (referring from China Biological Products Standard, which was calcµLated by the Arrhenius equation. For ELISA kit, 4 days storage at 37°C can be considered as 6 months at 2 - 8°C, which means 7 days at 37°C equaling 12 months at 2 - 8°C).
