What is Livagen?

Livagen is a tetrapeptide bioregulator (Lys-Glu-Asp-Ala) developed by the Khavinson institute for liver and haematopoietic system applications. Studied for chromatin remodelling, hepatocyte proliferation, haematopoietic stem cell support, and geroprotection. Research use only.

Research Applications

Hepatocyte Biology

Proliferation, metabolic enzyme expression, liver regeneration models

Haematopoietic Research

Stem cell support, colony-forming unit assays, bone marrow models

Immune Modulation

Lymphocyte proliferation, cytokine profiles, innate immune activation

Chromatin & Epigenetic Research

Heterochromatin remodelling, gene accessibility, age-related silencing

Liver Geroprotection

Age-related hepatic decline, lipofuscin accumulation, fibrosis prevention

Frequently Asked Questions

How do I reconstitute Livagen?
Add 1–2 mL bacteriostatic water to the lyophilized vial and swirl gently. Dissolves within 1 minute.
How should Livagen be stored?
Store lyophilized vials at −20°C. Reconstituted solution is stable at 2–8°C for up to 4 weeks.
What makes Livagen different from other bioregulators?
Livagen targets both liver and haematopoietic tissues, making it distinctive among Khavinson bioregulators. Research by the St. Petersburg institute suggests it promotes chromatin decondensation, activating age-silenced genes in these tissues.
