Our testing lab confirms peptides sequential signatures

Lyophilized Peptides: These peptides are freeze-dried, a process that not only extends shelf life but also preserves the purity and integrity of the peptides during storage.

Non-Lyophilized Peptides: Offered as a dry powder, these peptides, while not as extensively processed as lyophilized peptides, still maintain a high level of purity. Their stability, though not as enhanced as in lyophilized form, is sufficient for maintaining quality under proper storage conditions.

98.5% vs. 99% Purity: Both grades are manufactured in our US-based facility and tested for quality at a third party lab. While the 99%+ purity grade is our highest reference grade product line, the 98.5% purity variants still exceed US pharmaceutical standards.

Livagen Peptide Description

Livagen is a tetrapeptide bioregulator composed of the amino acid sequence Lys-Glu-Asp-Ala. This laboratory-grade peptide demonstrates remarkable biological activity in experimental settings, particularly in hepatocyte culture studies.

Research shows that nanomolar concentrations of Livagen significantly enhance protein synthesis rates in aged hepatocyte cultures, restoring functionality comparable to young specimens. A notable property of this peptide is its ability to restore disrupted intracellular circadian rhythms of biosynthesis.

Livagen’s mechanism of action involves the endogenous opioid system, where it effectively inhibits enkephalin-degrading enzymes with superior efficiency compared to conventional peptidase inhibitors. Interestingly, the peptide does not directly interact with opioid receptors, suggesting its biological effects occur through alternative pathways.

This unique bioregulator influences chromatin structure through selective heterochromatin modifications, enabling the activation of previously silenced genes in cellular models. Livagen represents a valuable research tool for laboratories investigating cellular rejuvenation mechanisms and protein synthesis pathways.

Research

Livagen (Lys-Glu-Asp-Ala) Research

Livagen is a peptide bioregulator that has been studied for its potential therapeutic effects on chromatin modification, genomic stability, enzyme activity, and its role in various conditions.

Chromatin Modification and Genomic Stability

Livagen has been shown to influence chromatin structure by inducing deheterochromatinization, which involves the decondensation of heterochromatin. This process can activate ribosomal genes and potentially counteract aging-related chromatin changes, offering new avenues for treating aging-relatedย diseases.[1]

In patients with atherosclerosis, Livagen, both alone and in combination with cobalt ions, has been found to normalize genomic instability. This suggests its potential in reducing chromatin condensation and improving genomic health in atherosclerosis patients.[2]

Effects on Cardiovascular Conditions

Livagen, particularly when combined with cobalt ions, enhances the activity of nucleolar organizer regions (NORs) and increases the frequency of acrocentric chromosome associations in lymphocytes. This indicates a decondensation effect on chromatin, which may help reactivate inactivated genes, providing a protective effect in Hypertrophic Cardiomyopathy (HCM) patients.[3]

Enzyme Activity and Opioid System Interaction

Livagen inhibits enkephalin-degrading enzymes in human serum more effectively than some known peptidase inhibitors. However, it does not interact with mu- or delta-opioid receptors, suggesting its action is specific to enzyme inhibition rather than receptor interaction.[4][5]

Digestive Enzyme Activity

Livagen administration affects digestive enzyme activity differently based on age. In young rats, it reduces enzyme activity, while in older rats, it increases activity, bringing it closer to levels observed in young control animals. This suggests Livagen’s potential in modulating enzyme activity to maintain digestive health across different ages.[6]
