How it works
-
Peptide-DNA Interaction
Gene-Level Bioregulation
Cartalax is a short tripeptide (Ala-Glu-Asp). Research from the Khavinson group proposes that peptides of this class interact with chromatin and the promoter regions of specific genes, influencing transcription of tissue-specific proteins.
- Proposed binding to promoter regions of specific genes
- Associated with sequence-specific changes in gene expression
- Studied as an epigenetic-level regulator rather than a receptor agonist
-
Connective Tissue
Cartilage & Chondrocyte Focus
AED is studied as a bioregulator for cartilage and connective tissue. Cell-culture research has examined its effect on chondrocytes and fibroblasts, with proliferation and extracellular-matrix markers as measured endpoints.
- Studied in chondrocyte and fibroblast cultures
- Extracellular-matrix markers measured
- Proliferation endpoints measured
-
Cellular Aging
Aging Cell-Culture Models
Short-peptide bioregulators are investigated in models of cellular aging. For AED, studies have examined markers of proliferation and apoptosis in aging connective-tissue cell cultures.
- Studied in aging cell-culture models
- Apoptosis markers measured
- Investigated alongside other short-peptide bioregulators

Frequently asked questions
What is Cartalax?
Cartalax is a synthetic tripeptide, Ala-Glu-Asp (AED), from the short-peptide bioregulator research of the Khavinson group. It is studied in cartilage and connective-tissue models.
How does it relate to Pinealon and Epithalon?
All three are short-peptide bioregulators from the same line of research. Pinealon (EDR) is studied in neuronal models, Epithalon (AEDG) in pineal and telomere research, and Cartalax (AED) in cartilage and connective-tissue models.
What is the molecular weight and purity?
Cartalax has a molecular weight of 333.29 g/mol. Every vial is supplied at ≥99% purity, verified by HPLC, with a Certificate of Analysis included.
How should it be stored?
Store lyophilized vials at -20°C for long-term stability, protected from light and moisture.
Is this product for human use?
No. Cartalax is sold strictly as a research compound for laboratory and in-vitro use only. It is not intended for human or animal consumption, diagnosis, or treatment.
