Hepatic & Immune Bioregulator

Livagen is the tetrapeptide Lys-Glu-Asp-Ala (KEDA), molecular weight approximately 461 Da, originally derived from research on bovine liver tissue extracts. It is described as a dual-action hepatic and immune bioregulator, with proposed activity in both liver parenchyma and lymphocyte populations.

Unlike the majority of named bioregulators in this class, which share the Ala-Glu-Asp N-terminal tripeptide, Livagen begins with the basic residue lysine, giving it a distinct electrostatic and structural profile. That places it in the KED group with Vesugen and Testagen (KED), Pancreagen (KEDW), and Prostamax (KEDP) rather than the AED group. Against Ovagen, the other liver-oriented peptide, Livagen is the longer molecule and the one carrying the immune component. Its most frequently cited research concerns chromatin decondensation and the resulting influence on gene accessibility, studied alongside hepatocyte function and lymphocyte activation.

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

Common Questions

Livagen FAQ

What is Livagen?+
Livagen is a Hepatic & Immune Bioregulator supplied for laboratory research. Dual-action bioregulator studied in vitro for chromatin decondensation pathway modeling, liver function signaling research, and immune cell activation mechanism analysis.
How does the Livagen bioregulator work?+
Livagen (Lys-Glu-Asp-Ala) is a liver and immune peptide bioregulator studied for chromatin-decondensation and gene-activation signaling, with noted research interest in both hepatic and immune cells.
How is Livagen different from Ovagen?+
Livagen is the tetrapeptide Lys-Glu-Asp-Ala (KEDA), about 461 Da, and is described as a dual hepatic and immune bioregulator. Ovagen is the shorter tripeptide Glu-Asp-Leu (EDL) and is studied in a liver and gastrointestinal-epithelium context only. Livagen also begins with lysine rather than the alanine that opens most peptides in this series, giving it a different structural profile.
What is lyophilized Livagen, and how is it reconstituted?+
Livagen 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 Livagen be stored?+
Store the lyophilized Livagen 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 Livagen, and how is it tested?+
Every batch of Livagen 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.
