VIP (5mg & 10mg)

VIP (5mg & 10mg) is a lyophilized research peptide synthesized, purified, and lyophilized in the USA. Each production batch is purified by repeated rounds of reverse-phase HPLC and identity-confirmed by mass spectrometry.

VIP (5mg & 10mg) is a lyophilized research peptide supplied for in-vitro laboratory investigation.

Studies of VIP (5mg & 10mg) typically combine purity verification with functional assays to support reproducible results.

Researchers evaluating VIP (5mg & 10mg) document batch COA data and storage conditions as part of experimental design.

Each vial contains lyophilized peptide at the labeled quantity, and wholesale orders are packed in boxes of ten vials at a single per-vial price.

Quality assurance: every batch is purified by reversed-phase high-performance liquid chromatography and identity-confirmed by mass spectrometry, with purity above 99%. Lot-specific certificates of analysis are available on request. Store lyophilized vials at -20°C, protected from light and moisture; reconstitute with bacteriostatic water immediately before use and avoid repeated freeze-thaw cycles. For in-vitro laboratory research use only —not for human or veterinary use.

Research & Literature

The following peer-reviewed studies and reference documents are commonly consulted by researchers working with VIP (5mg & 10mg). Summaries are provided for orientation only and reflect the cited sources.

Vasoactive intestinal peptide: a neuropeptide with pleiotropic immune functions^[1] —This review describes vasoactive intestinal peptide (VIP) as a neuropeptide with pleiotropic immune functions. The authors discuss VIP's effects on immune cell subsets and inflammatory responses. The article establishes VIP as an important neuro-immune mediator relevant to therapeutic development. (Amino acids 2013)

Therapeutical approaches of vasoactive intestinal peptide as a pleiotropic immunomodulator^[2] —This review discusses therapeutic approaches that use vasoactive intestinal peptide (VIP) as a pleiotropic immunomodulator. The authors examine VIP's potential in inflammatory and autoimmune conditions. The article highlights the translational promise of VIP-based strategies. (Current pharmaceutical design 2007)

A Historical Review of Vasoactive Intestinal Peptide and Pituitary Adenylate Cyclase-Activating Polypeptide in Sepsis^[3] —This historical review covers research on vasoactive intestinal peptide (VIP) and pituitary adenylate cyclase-activating polypeptide (PACAP) in sepsis. The authors trace the evolution of findings on these neuropeptides in systemic inflammation. The review underscores their potential relevance to sepsis pathophysiology and treatment. (Biology 2026)

Regulatory effects of vasoactive intestinal peptide on cytokine production in central and peripheral lymphoid organs^[4] —This study examined the regulatory effects of vasoactive intestinal peptide (VIP) on cytokine production in central and peripheral lymphoid organs. The authors report that VIP modulates cytokine expression in these immune tissues. The findings support VIP's role as a regulator of immune responses. (Advances in neuroimmunology 1996)
