This assay has high sensitivity and excellent specificity for detection of Vasoactive Intestinal Peptide (VIP). No significant cross-reactivity or interference between Vasoactive Intestinal Peptide (VIP) and analogues was observed.

For unopened kit: All the reagents should be kept according to the labels on vials. The Standard, Detection Reagent A, Detection Reagent B and the 96-well strip plate should be stored at -20 degree C upon receipt while the others should be at 4 degree C. For opened kit: When the kit is opened, the remaining reagents still need to be stored according to the above storage condition. Besides, please return the unused wells to the foil pouch containing the desiccant pack, and reseal along entire edge of zip-seal. The stability of kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition. To minimize extra influence on the performance, operation procedures and lab conditions, especially room temperature, air humidity, incubator temperature should be strictly controlled. It is also strongly suggested that the whole assay is performed by the same operator from the beginning to the end.

Samples: Serum, plasma and other biological fluids. Assay Type: Competitive. Detection Range: 6.17-500pg/mL. Sensitivity: Typically less than 2.77pg/mL.

Precision: 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% . Assay Procedure Summary: 1. Prepare all reagents, samples and standards;. 2. Add 50uL standard or sample to each well. And then add 50uL prepared Detection Reagent A immediately. Shake and mix. Incubate 1 hour at 37 degree C;. 3. Aspirate and wash 3 times;. 4. Add 100uL prepared Detection Reagent B. Incubate 30 minutes at 37 degree C;. 5. Aspirate and wash 5 times;. 6. Add 90uL Substrate Solution. Incubate 15-25 minutes at 37 degree C;. 7. Add 50uL Stop Solution. Read at 450 nm immediately.

Principle of the Assay: 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.

The protein encoded by this gene belongs to the glucagon family. It stimulates myocardial contractility, causes vasodilation, increases glycogenolysis, lowers arterial blood pressure and relaxes the smooth muscle of trachea, stomach and gall bladder. The protein also acts as an antimicrobial peptide with antibacterial and antifungal activity. Alternative splicing occurs at this locus and two transcript variants encoding distinct isoforms have been identified. [provided by RefSeq, Nov 2014]

VIP: VIP causes vasodilation, lowers arterial blood pressure, stimulates myocardial contractility, increases glycogenolysis and relaxes the smooth muscle of trachea, stomach and gall bladder. Belongs to the glucagon family. 2 isoforms of the human protein are produced by alternative splicing. Protein type: Secreted, signal peptide; Secreted. Chromosomal Location of Human Ortholog: 6q25. Cellular Component: cell soma; extracellular region. Molecular Function: neuropeptide hormone activity; protein binding; hormone activity. Biological Process: G-protein coupled receptor protein signaling pathway; regulation of protein localization; learning and/or memory; negative regulation of smooth muscle cell proliferation; mRNA stabilization; negative regulation of potassium ion transport; positive regulation of cell proliferation; positive regulation of protein catabolic process; regulation of signal transduction; positive regulation of endothelial cell proliferation; regulation of sensory perception of pain; body fluid secretion; positive regulation of vasodilation; negative regulation of apoptosis
