VIP ELISA Kit (Rat)

Intra-assay Precision (Precision within an assay) : 3 samples with low, middle and high level Vasoactive Intestinal Peptide (VIP) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays) : 3 samples with low, middle and high level Vasoactive Intestinal Peptide (VIP) were tested on 3 different plates, 8 replicates in each plate. CV (%) = SD/meanX100 Intra-Assay: CV<10% Inter-Assay: CV<12%

VIP causes vasodilation, lowers arterial blood pressure, stimulates myocardial contractility, increases glycogenolysis and relaxes the smooth muscle of trachea, stomach and gall bladder.

This assay employs the competitive inhibition enzyme immunoassay technique. A monoclonal antibody specific to Vasoactive Intestinal Peptide (VIP) has been pre-coated onto a microplate. A competitive inhibition reaction is launched between biotin labeled Vasoactive Intestinal Peptide (VIP) and unlabeled Vasoactive Intestinal Peptide (VIP) (Standards or samples) with the pre-coated antibody specific to Vasoactive Intestinal Peptide (VIP) . After incubation the unbound conjugate is washed off. Next, avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. The amount of bound HRP conjugate is reverse proportional to the concentration of Vasoactive Intestinal Peptide (VIP) in the sample. After addition of the substrate solution, the intensity of color developed is reverse proportional to the concentration of Vasoactive Intestinal Peptide (VIP) in the sample.
