Livagen: research overview
Livagen 20 mg is a short peptide from the Khavinson bioregulator group, supplied as a lyophilized research reagent. Every batch has a purity of 99% or higher by HPLC, a molecular mass confirmed by MS, so you start your work with verified material from the very first vial.
What Livagen is
Structure and origin
Livagen is a peptide, a short chain of amino acids linked by peptide bonds. It belongs to the group of bioregulators developed in the work of Khavinson and his team. The literature describes it as a bioregulator of liver tissue, which is why research on Livagen centres on the cells of that tissue.
Mechanism described in research
Descriptions in the literature present Khavinson bioregulators as short peptides that influence the activity of cells in the tissue they are associated with. For Livagen, the work focuses on liver cells in in vitro models. The exact mechanism is still under investigation, so it is best to interpret results within your own research design.
Research areas
- liver cell biology in in vitro models,
- regulation of tissue cell activity,
- comparative studies of Khavinson bioregulators derived from different tissues,
- preparation, storage and reconstitution of peptides in the laboratory.

Laboratory handling
Storage
- Lyophilizate: -20 °C, in a tightly sealed container, protected from light and moisture.
- After reconstitution: 2-8 °C.
- Avoid repeated freezing and thawing of the solution, as it shortens the stability of the peptide.
Before opening, let the vial reach room temperature so that no condensation forms on the cold material. Withdraw the required amount in one step, so the remaining solution is not exposed to temperature changes more than necessary.
Reconstitution: the role of water and acetic acid
Water, preferably bacteriostatic water prepared for laboratory work, is the base solvent for Livagen. If the peptide dissolves poorly in pure water, use dilute acetic acid. Acidification increases the solubility of many peptides, and water remains the base solvent for any further dilution. You can calculate your working concentration from the peptide mass and the volume of solvent.
Batch quality
Every batch goes through two checks:
- HPLC: purity of at least 99%,
- MS: confirmation of the molecular mass
