Description
Rat IL-12 p40 ELISA Kit
The Rat IL-12 p40 ELISA Kit is a specialized assay designed to quantitatively measure interleukin-12 (IL-12) p40 levels in a variety of rat biological samples.
IL-12 p40 is an essential subunit of the heterodimeric cytokine IL-12, playing a crucial role in immune responses by promoting the differentiation of T cells, enhancing natural killer cell activity, and inducing interferon-gamma production. Monitoring IL-12 p40 levels is integral to understanding the immune system's regulation and function, particularly in response to infections and autoimmune disorders. Our ELISA kit offers unparalleled sensitivity and specificity, ensuring accurate and reproducible results for your research needs. Manufactured under rigorous quality control standards, this kit provides robust performance and user-friendly protocols, enabling researchers to investigate the complex roles of IL-12 p40 in immune modulation with confidence. Trust the Rat IL-12 p40 ELISA Kit to advance your immunology research and uncover new insights into immune regulation and inflammatory processes.

This ELISA kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Rat IL-12 p40. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Rat IL-12 p40 and Avidin-Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate well and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Rat IL-12 p40, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentration of Rat IL-12 p40. You can calculate the concentration of Rat IL-12 p40 in the samples by comparing the OD of the samples to the standard curve.
Precision
Intra-assay Precision (Precision within an assay): 3 samples with low, mid range and high level Rat IL-12 p40 were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, mid range and high level Rat IL-12 p40 were tested on 3 different plates, 20 replicates in each plate.
