Vesugen

Vascular Peptide Bioregulator

Vesugen is the tripeptide Lys-Glu-Asp (KED), molecular weight approximately 390 Da, developed from research involving vascular tissue-derived peptide fractions. It is the vascular member of the Khavinson bioregulator series, proposed to modulate gene expression in vascular endothelial cells, the cell layer lining blood vessel walls.

Vesugen is structurally notable for a reason worth knowing before ordering: its KED sequence is identical to that of Testagen, the testicular-oriented peptide from the same series. The two are the same molecule described for different tissues, which is a recognized open question for the organ-specificity hypothesis underpinning the class. KED is also the core that Livagen (KEDA), Pancreagen (KEDW), and Prostamax (KEDP) extend by one residue. In vitro and animal studies examine endothelial-cell function, vessel-wall integrity signaling, and microcirculation modeling.

Supplied as a lyophilized 10-vial 20mg kit for in vitro research use only.

Common Questions

Vesugen FAQ

What is Vesugen?+
Vesugen is a Vascular Peptide Bioregulator supplied for laboratory research. Vascular bioregulator studied in vitro for endothelial cell function pathway modeling, vessel wall integrity signaling research, and microcirculation mechanism analysis.
What tissue does the Vesugen bioregulator target?+
Vesugen (Lys-Glu-Asp) is a peptide bioregulator based on vascular tissue, studied for endothelial function and vessel-wall-integrity signaling.
Why do Vesugen and Testagen have the same sequence?+
They do share a sequence: both Vesugen and Testagen are the tripeptide Lys-Glu-Asp (KED), roughly 390 Da. They are the same molecule described for different target tissues, Vesugen for vascular endothelium and Testagen for testicular tissue. The research literature treats this as an open question for the organ-specificity hypothesis behind the peptide bioregulator class, so the two differ in intended research context rather than in chemistry.
What is lyophilized Vesugen, and how is it reconstituted?+
Vesugen is supplied as a lyophilized (freeze-dried) powder, a dehydrated form that keeps the peptide stable during shipping and storage. In the laboratory it is reconstituted (returned to liquid form) using a solvent such as bacteriostatic water, added slowly against the side of the vial, which is then swirled gently, never shaken, until the powder fully dissolves. All handling is for in vitro research use only.
How should Vesugen be stored?+
Store the lyophilized Vesugen powder at -20°C, protected from light and moisture, where it remains stable long-term. Once reconstituted, keep it refrigerated (2-8°C) and use it within the timeframe appropriate for your research protocol.
What is the purity of Vesugen, and how is it tested?+
Every batch of Vesugen is produced to a purity of 99% or higher. Purity and molecular identity are verified using standard analytical methods: high-performance liquid chromatography (HPLC) to measure purity, and mass spectrometry (MS) to confirm the peptide's molecular weight.
