VIP (Vasoactive Intestinal Peptide)
VIP is an endogenous 28-amino-acid neuropeptide distributed across the nervous, gastrointestinal, cardiovascular, and immune systems. It is studied in models of smooth muscle, secretion, neuronal communication, and immune regulation.
VIP belongs to the secretin/glucagon family and signals mainly through VPAC1 and VPAC2. Responses depend on receptor expression, tissue context, concentration, and rapid enzymatic degradation.
The classical pathway involves Gs-coupled receptors, adenylyl cyclase, and increased cAMP. Ion channels, smooth-muscle tone, secretion, and inflammatory mediators are studied in different models, but observations are not universal across tissues.
Common areas include VPAC1/VPAC2 pharmacology, desensitization, proteolysis, intestinal and pulmonary physiology, neuroimmune interactions, vascular models, and comparison of native VIP with stabilized analogues.
Basic VIP physiology is extensively described, but applied evidence is heterogeneous. Pharmacokinetic instability and broad receptor distribution complicate translation between models and do not make this material a clinically validated product.
VIP is susceptible to proteolysis and surface adsorption. Document dissolution conditions, suitable containers, temperature control, limited freeze-thaw cycles, and stability for the specific assay.
The label, lot number, declared vial amount, and batch-specific documentation are the authoritative references for the supplied material. Any certificate should be matched to the lot number on the vial. A purity result describes analytical composition; it does not establish sterility, clinical safety, or suitability for human use.
Published research about the molecule VIP (Vasoactive Intestinal Peptide) describes specific experimental materials, formulations, doses, populations, and controlled conditions. Those findings cannot be transferred automatically to this Peptara Lab research material and are not a promise of clinical effect.
VIP (Vasoactive Intestinal Peptide) is supplied exclusively for controlled laboratory and in vitro research. The experimental design, solvent, concentration, and handling procedure must be determined by qualified personnel under an approved institutional protocol.
Record the product title, lot number, vial amount, receipt date, opening date, storage conditions, operator, and experimental use in the laboratory log.
Confirm solvent and container compatibility, use appropriate blanks and reference standards, and document any deviation from the approved method.
Orders are prepared on business days after payment and stock confirmation. You will be contacted if an item requires additional processing time.
Products are packed to reduce movement, light exposure, and damage during transport. Inspect the parcel and product label after delivery.
Tracking information is provided when supported by the selected carrier. Delivery time depends on the destination and courier service.
Available delivery methods, final shipping cost, and the latest estimated delivery window are shown at checkout.
VIP (Vasoactive Intestinal Peptide) is offered exclusively for laboratory and in vitro research. It is not intended for human or veterinary use.
VIP is not merely a vascular peptide. It is a pleiotropic mediator whose effects vary by receptor and tissue, so experiments require receptor and negative controls.
No. Products in this catalog are research materials and are not presented as medicines, foods, cosmetics, or dietary supplements.
Follow the conditions printed on the label and any batch documentation. Keep the container sealed and protect it from light, heat, moisture, contamination, and repeated temperature changes.
The variant indicates the amount of material in the vial. Choose only according to the requirements of your validated laboratory protocol; it is not a dosage recommendation.
Where batch-specific documentation is available, it can be requested from Peptara Lab support before purchase. Always match any document to the lot number on the received product.
After payment and stock confirmation, in-stock orders are normally prepared for dispatch within 1–2 business days. Courier transit time is separate and depends on destination and service.
Do not use the material. Photograph the outer parcel, protective packaging, label, lot number, and damage, keep all packaging, and contact Peptara Lab support promptly for review.
