VIP (Vasoactive Intestinal Peptide) is a synthetic research peptide supplied as a lyophilized powder for controlled laboratory, analytical, and in-vitro research applications. Each vial contains 6mg of VIP.
Lot-specific analytical documentation is available through the Certificate of Analysis library. Researchers should review the applicable COA for identity, purity, test methods, and other reported quality parameters before beginning an experiment.
VIP is commonly used as a laboratory reference material in studies involving peptide-receptor interactions, VPAC receptor systems, ligand-binding behavior, and downstream molecular signaling. Any research involving VIP should be conducted by qualified personnel using validated laboratory procedures and appropriately controlled experimental models.
The primary concern for peptide researchers today is product purity. Nord-sci guarantees our product purity by performing independent testing of our products and providing those certifications for our customers in our product descriptions.

All products are produced using lyophilization (freeze-drying), a preservation method that allows peptides to remain fully stable during shipping for approximately 3-4 months. Once a peptide has been reconstituted with bacteriostatic water, it must be refrigerated to maintain integrity. After reconstitution, peptides typically remain stable for up to 30 days when stored properly.
Lyophilization, also referred to as cryodesiccation, is a specialized dehydration process in which peptides are first frozen and then exposed to a low-pressure environment. This causes the water within the vial to transition directly from a solid to a vapor (sublimation), leaving behind a dry, crystalline white material known as a lyophilized peptide. In this powdered form, peptides may be safely stored at room temperature until they are ready to be reconstituted with bacteriostatic water.
After delivery, peptides should be protected from heat and light. If use is expected within the near future (whether days, weeks, or a few months) refrigerated storage below 4°C (39°F) is generally sufficient. Lyophilized peptides are commonly stable at room temperature for several weeks or longer, making short-term ambient storage acceptable when use is anticipated within that timeframe.
For extended storage, ranging from several months to multiple years, freezing is strongly recommended. Storage at -80°C (-112°F) offers optimal long-term stability and helps preserve peptide structure and quality over time.

VIP is an endogenous peptide sequence first characterized through biochemical isolation and analytical research. Synthetic VIP is used as a reference material in controlled studies examining peptide structure, molecular recognition, receptor interactions, and associated signaling measurements.
VIP is principally associated with the VPAC1 and VPAC2 receptor families. Depending on the study design, researchers may use the peptide to examine ligand-binding affinity, receptor selectivity, concentration-dependent assay responses, second-messenger activity, or comparative behavior across experimental systems.
Research conclusions depend on the model, assay conditions, controls, analytical method, and material characterization. Results obtained in isolated cells, receptor assays, biochemical systems, or other laboratory models cannot be directly extrapolated to human or animal outcomes.
Important Research Notice: Lot-specific Certificates of Analysis are available to document reported identity, purity, and analytical results. Researchers should confirm that the applicable documentation satisfies their internal quality requirements before use.
THIS PRODUCT IS INTENDED EXCLUSIVELY FOR LABORATORY RESEARCH. NOT FOR HUMAN OR ANIMAL CONSUMPTION. NOT INTENDED FOR CLINICAL, DIAGNOSTIC, THERAPEUTIC, VETERINARY, FOOD, COSMETIC, OR SUPPLEMENT APPLICATIONS.
VIP may be used as a reference material in analytical workflows examining peptide identity, chromatographic behavior, mass characteristics, stability variables, and method performance. Study parameters should be documented in accordance with the laboratory’s validated procedures.
Controlled in-vitro systems may use VIP to investigate binding behavior involving VPAC1 or VPAC2 receptors. Common experimental variables include receptor expression, ligand concentration, incubation conditions, comparator compounds, and assay-specific response measurements.
VIP may be evaluated in laboratory assays designed to measure receptor-associated molecular events and downstream second-messenger activity. Experimental interpretation requires appropriate negative controls, positive controls, predefined endpoints, and validated analytical methods.
Researchers may include VIP in comparative studies involving related peptide ligands, receptor subtypes, analogs, or assay platforms. Consistent material handling, lot tracking, and standardized experimental conditions are necessary when comparing results across runs or cohorts.
VIP should be handled only by qualified laboratory personnel in appropriately equipped facilities. Laboratories should maintain documentation for receipt, storage, preparation, experimental use, and disposal.
Before beginning an experiment, researchers should verify:
Environmental conditions, assay design, sample preparation, instrumentation, and operator technique can affect experimental results. Laboratories should use consistent procedures and document deviations that may influence data interpretation.
