Description

The Rat Vasoactive Intestinal Peptide (VIP) ELISA Kit is a highly sensitive and reliable assay for the quantification of VIP peptide in serum, plasma, and tissue homogenates from Rattus norvegicus (Rat).

VIP peptide,a neuropeptide that is widely distributed in the central and peripheral nervous systems ,is known to play a critical role in the regulation of various physiological processes, particularly in the nervous system. Our ELISA kit is designed to accurately measure the levels of VIP peptides in biological samples, making it an essential tool for researchers in the field of neuroscience.

The detection range of the kit is 1.56 pg/mL-100 pg/mL, with a sensitivity of 0.39 pg/mL, ensuring precise and accurate quantification of VIP peptides in samples. The assay time is only 1-5 hours, and the sample volume required is minimal (50-100ul), making the kit highly efficient and suitable for high-throughput experiments.

The VIP ELISA kit uses a sandwich assay principle, which involves the use of a VIP-specific antibody to capture the peptide of interest, followed by the detection of the captured VIP peptide using a second VIP-specific antibody. The detection wavelength is 450 nm, and the results are easily obtained using a microplate reader.

Target Background

Function
(From Uniprot)
VIP causes vasodilation, lowers arterial blood pressure, stimulates myocardial contractility, increases glycogenolysis and relaxes the smooth muscle of trachea, stomach and gall bladder.; PHM-27 is a potent agonist of the calcitonin receptor CALCR, with similar efficacy as calcitonin. PHI also causes vasodilation.
