背景（Background）
ClinMax? ELISA Kit is convenient ready-to-use immunoassay Kit, specifically designed to quantitate human IL-12p70 that is present in complex biological samples, such as human serum, plasma, and cell culture supernates.
A comprehensive validation of the ELISA method was performed following the ICH M10 on bioanalytical method validation and the FDA’s bioanalytical method validation guidance for industry. This validation included assessments of linearity, accuracy, precision, dilution linearity, recovery, and the hook effect. For details information, please refer to the DS.
ClinMax? ELISA Kits are manufactured in a GMP-certified facility and comply to the ISO 13485 standard, ensuring a high level of quality and reliability.
应用说明（Application）
The kit is developed for quantitative detection of IL-12p70 in human serum and cell culture supernates.
It is for research use only.
重构方法（Reconstitution）
Please see Certificate of Analysis for details of reconstitution instruction and specific concentration.
存储（Storage）
The unopened kit is stable for 12 months from the date of manufacture if stored at 2°C to 8°C.
The opened kit should be stored per components table. The shelf life is 30 days from the date of opening.
原理（Assay Principles）
This assay kit is used to measure the concentrations of human Interleukin 2 (IL-12p70) by employing a standard sandwich-ELISA format. The microplate in the kit has been pre-coated with Anti- IL-12p70 Antibody. First add the standard samples provided in kit and your samples to the plate, next add detection antibody Biotin-Anti-IL-12p70 Antibody to the plate, incubate and wash the wells. After wash add HRP-Streptavidin to the plate, incubate and wash the wells. Lastly load the substrate into the wells and color develops in proportion to the amount of Interferon-γ bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450nm and 630nm.
典型数据-Typical Data Please refer to DS document for The assay protocol.
For each experiment, each ELISA plate needs to set the standard curve. The minimum detectable concentration of CRS-B009 is less than 2.0 pg/mL.
背景（Background）：IL-12p70
Interleukin 12, IL-12(P70), IL-12p70
Biologically active IL-12 is a heterodimeric cytokine composed of p35 and p40 subunits (also known as IL-12p70). IL-12 is mainly produced by activated monocytes, macrophages, and DCs. IL-12, through STAT4 activation, is essential for the differentiation and maintenance of Th1 effector cells, which then produce high levels of IFN-γ, TNF-α, and IL-2. These cytokines, in turn, promote T-cell responses and macrophage activation that contribute to inflammatory responses. IL-12 is also important for enhancing the cytotoxicity mediated by NK cells. IL-12 has been shown to play a critical role in the pathogenesis of immune-related diseases, particularly autoimmune and inflammatory conditions such as RA, atherosclerosis, and MS.
