Overview

VIP 5 mg Research Peptide is a vasoactive intestinal peptide (VIP) supplied by Ascension Labs USA as a lyophilized, research-use-only reagent. VIP is widely recognized in the scientific literature as a neuropeptide involved in enteric signaling, motility, secretory responses, and microvascular tone, making it relevant to non-clinical models that focus on gastrointestinal and microvascular pathways.

This product is designated strictly as Research Use Only (RUO). It is not intended for human or veterinary use, clinical application, or diagnostic purposes. All experimental parameters, including concentration, exposure duration, and assay selection, must be determined by qualified investigators according to primary literature and institutional SOPs.

Technical summary

VIP is a peptide that interacts with specific receptors in the GI and vascular systems, and is used experimentally in:

In-vitro models of GI smooth muscle and motility, where contractility and motility-related markers are monitored.
Systems examining secretory responses and barrier behavior in intestinal or epithelial tissues.
Preclinical models of microvascular and endothelial function, where vasoactive signaling and perfusion-related endpoints are of interest.

Ascension Labs USA supplies VIP 5 mg as a lyophilized research peptide. Reconstitution procedures, working concentrations, and specific assay formats are defined by the end user based on their internal protocols and scientific objectives.

Research focus & potential applications

Representative non-clinical research themes for VIP include:

GI motility and enteric signaling — models where enteric neuronal input, motility-related endpoints, and smooth muscle responses are core readouts.
Secretory and barrier function — in-vitro and preclinical systems tracking secretion, barrier tightness, or epithelial behavior under VIP exposure.
Microvascular and endothelial pathways — experiments examining how vasoactive signaling influences microvascular tone, perfusion, and related markers.
GI & microvascular interaction — combined frameworks where tissue-level GI outcomes and microvascular integrity are evaluated together.

All applications remain non-clinical; VIP from Ascension Labs USA is supplied exclusively as a research-use-only reagent for laboratory environments.

Suggested experimental context

Ascension Labs USA does not provide dosing, administration, or clinical guidance. However, VIP is often incorporated into study designs that:

Compare baseline vs. stimulated conditions — assessing differences in motility, secretion, or vascular markers with and without VIP exposure.
Pair VIP with tissue-repair or mitochondrial reagents — for example, as part of GI- and microvascular-focused panels such as the Gastro Support Research Stack, where VIP is evaluated alongside BPC-157/TB-500 or SS-31.
Map receptor-mediated responses — focusing on downstream signaling cascades, second messengers, or expression changes in response to VIP in controlled in-vitro systems.

Design, execution, and interpretation of all experiments are the responsibility of the investigator and should be grounded in appropriate scientific references and institutional oversight.

Storage & handling

Storage and handling requirements may vary by lot. In general, lyophilized RUO peptides:

Are stored frozen in a dry environment, protected from light.
Are reconstituted immediately prior to use in suitable diluents, as defined by internal SOPs and experimental needs.
Should be aliquoted and refrozen only according to institutional guidelines to minimize freeze–thaw cycles.
Are handled exclusively by trained personnel using appropriate PPE in properly equipped research laboratories.

Always review the documentation supplied with each lot and follow your institution’s safety, storage, and waste-disposal procedures.

Why choose VIP from Ascension Labs USA

GI & vasoactive focus — VIP is well suited for non-clinical models of gastrointestinal tissue behavior, motility, secretory responses, and microvascular signaling.
