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

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.
