Description
Rat MTL (Motilin) ELISA Kit
The Rat MTL (Motilin) ELISA Kit is a specialized assay designed for the quantitative measurement of Motilin levels in various rat biological samples. Motilin, a gastrointestinal hormone produced in the small intestine, plays a crucial role in regulating gastrointestinal motility by stimulating smooth muscle contraction in the digestive tract. This hormone helps coordinate the movement of food and waste through the digestive system, contributing to the digestive process and overall gut health. This ELISA kit enables researchers to accurately quantify Motilin levels in rat samples, providing valuable insights into gastrointestinal function, motility disorders, and related physiological processes.
With exceptional sensitivity and specificity, the Rat MTL ELISA Kit offers reliable and reproducible results, allowing for in-depth investigations into motilin's biological effects. Manufactured under stringent quality control standards, this kit ensures robust performance and ease of use, making it an excellent tool for research focused on gastrointestinal physiology and digestive health in rat models.

This ELISA kit uses the Competitive-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with MTL. During the reaction, MTL in the sample or standard competes with a fixed amount of MTL on the solid phase supporter for sites on the Biotinylated Detection Ab specific to MTL. Excess conjugate and unbound sample or standard are washed away, and Avidin-Horseradish Peroxidase (HRP) conjugate are added to each micro plate well and incubated. Then a TMB substrate solution is added to each well. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns from blue to yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The concentration of MTL in tested samples can be calculated 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 MTL were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, mid range and high level MTL were tested on 3 different plates, 20 replicates in each plate.
