Welcome to Liaocheng Yixin Company, your trusted source for premium livagen 20mg peptide for research. As a specialized peptide synthesis manufacturer operating from our facility at No. 9 Lushan Road, Dongcheng Street, Liaocheng Economic and Technological Development Zone, Shandong Province, we provide high-quality research compounds for the global scientific community.

Livagen is a synthetic tetrapeptide bioregulator with the amino acid sequence Lys-Glu-Asp-Ala (KEDA) . It has been the subject of extensive research for its ability to influence chromatin structure, gene expression, and cellular homeostasis . With a molecular weight of 461.47 g/mol, this tetrapeptide represents a focused research tool for studies in epigenetics, aging, and cellular regeneration . Our livagen 20mg peptide for research offers investigators a reliable, high-purity compound for chromatin activation and gene expression studies.

What is Livagen?

Livagen is a tetrapeptide with the sequence Lys-Glu-Asp-Ala (KEDA) . It belongs to a class of peptide bioregulators investigated for their ability to modulate chromatin structure and gene expression. Unlike some other peptides in this class, Livagen is classified as a weakly hydrolyzed peptide, meaning it is not easily broken down by digestive enzymes .

Mechanism of Action in Research

Livagen exerts its biological effects through several distinct mechanisms that make it a valuable tool for epigenetics and aging research:

Chromatin Activation and De-heterochromatinization

Research has demonstrated that Livagen induces chromatin activation in lymphocytes from older individuals . The peptide promotes decondensation of heterochromatin (de-heterochromatinization), which releases genes that have been silenced through age-related chromatin condensation . Specifically, Livagen has been shown to:

Activate ribosomal genes – increasing the number of nucleolar organizer regions and nucleoli per cell
Decondense pericentromeric structural heterochromatin – particularly on chromosomes 1 and 9
Release genes repressed through heterochromatinization – reversing age-related gene silencing

Hepatocyte Function and Protein Synthesis

In experiments with rat liver cells, Livagen has demonstrated significant biological activity. At nanomolar concentrations, the peptide increased the rate of protein synthesis in hepatocyte cultures from older animals to levels approaching those of young rat liver cells . Research confirms that Livagen stimulates structural and functional homeostasis in liver cell populations .

Enkephalin-Degrading Enzyme Inhibition

Livagen has been shown to inhibit enkephalin-degrading enzymes in human serum with an IC50 of 20 µM, proving more effective than some well-known peptidase inhibitors . However, Livagen does not interact directly with μ- or δ-opioid receptors, suggesting its mechanism involves indirect modulation of the endogenous opioid system .

Tissue-Specific Action

Studies have confirmed that Livagen, like other peptide bioregulators, exhibits tissue-specific effects in organ-typical culture systems, including liver and lymphoid tissues .

Scientific Research Applications

Livagen has been studied across multiple research domains:

Aging and Epigenetics Research

Livagen is used to investigate mechanisms of age-related chromatin condensation and gene silencing. Studies in lymphocytes from elderly individuals show that Livagen induces reactivation of ribosomal genes and decondensation of heterochromatin . This makes Livagen a relevant tool for research exploring the epigenetic aspects of aging and potential interventions to restore gene expression patterns.

Liver Physiology and Regeneration

Research in organotypic liver cultures demonstrates that Livagen stimulates structural and functional homeostasis, directs activity toward the stabilization of morphological integrity, and reinforces cellular and intracellular regeneration processes . The peptide increased protein synthesis rates in hepatocytes from older animals to levels approaching those of young cells .

Digestive Enzyme Regulation

Livagen has been studied for its effects on digestive enzyme activity. In young animals, the peptide reduces digestive enzyme activity, while in older animals it increases enzyme activity to levels approaching those of younger controls .

Opioid System Research

Livagen has been investigated for its potential role in modulating the endogenous opioid system through inhibition of enkephalin-degrading enzymes. This has implications for research into stress-induced and psychosomatic disorders . livagen 20mg peptide for research

Chromatin Structure Studies

Livagen is frequently used to investigate interactions between peptide bioregulators and chromatin structure, examining how peptide signals can influence gene expression at the level of chromatin accessibility .
