Description
Rat AR (Amphiregulin) ELISA Kit
The Rat AR (Amphiregulin) ELISA Kit is a specialized assay tool designed for the precise quantification of Amphiregulin levels in various biological samples obtained from rat models.
Amphiregulin is a member of the epidermal growth factor (EGF) family, known for its crucial regulatory roles in promoting cell growth, proliferation, differentiation, and migration. Its functions extend to diverse biological processes and mechanisms within the body. This ELISA kit, crafted by Assay Genie, ensures exceptional sensitivity and specificity, enabling researchers to obtain accurate and reproducible results. With robust performance and ease of use, this kit is manufactured under stringent quality control measures, making it an ideal choice for research studies focused on understanding the biological activities of Amphiregulin in rats and its implications in various physiological 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 AR. 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 AR 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 AR, 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 AR. You can calculate the concentration of Rat AR 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 AR were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, mid range and high level Rat AR were tested on 3 different plates, 20 replicates in each plate.
