What is Cartalax?
Cartalax is a synthetic short-chain peptide composed of alanine, glutamic acid, and aspartic acid (Ala-Glu-Asp). It is categorized as a peptide bioregulator and has been investigated for its potential role in supporting cellular processes associated with cartilage and connective-tissue biology. Research surrounding Cartalax has explored its interaction with cellular regulatory mechanisms, tissue-related processes, and age-associated changes at the cellular level. As a small peptide, Cartalax is of interest in research involving cellular signaling, gene-expression regulation, and the biological mechanisms involved in maintaining connective-tissue function. Current interest in Cartalax remains primarily within preclinical and laboratory research, where researchers continue to investigate its properties and potential biological activity.
How is Cartalax studied in the lab?
Work on this short-peptide family uses cultured cells, cell-free DNA-binding measurements and molecular modelling, with peptide uptake, binding selectivity and transcript levels as the reported endpoints.4, 5
What has preclinical research reported?
Cellular aging and gene expression
One of the better-characterized areas of research involving AED is cellular aging and gene expression. A 2020 study in Molecular Biology Reports investigated Ala-Glu-Asp alongside KED and KE in human embryonic bone-marrow mesenchymal stem-cell cultures. The researchers examined genes associated with cellular aging and signaling, including IGF1, FOXO1, TERT, TNKS2, and NFκB. AED produced changes in the expression of several of these genes in the experimental cell-aging models.
Kidney-cell and tissue-culture research
Earlier research examined T-31 (AED) in primary kidney-cell cultures undergoing in-vitro aging. The study evaluated markers associated with cell renewal, apoptosis, extracellular-matrix remodeling, and immune response. The researchers reported that T-31 influenced cell-renewal processes and expression of markers including Ki-67 and p53.
A separate 2015 study investigated T-31 (AED) in organotypic kidney tissue cultures from young and old rats. AED was reported to stimulate cellular proliferation and reduce apoptosis-related signaling, although its effects were less pronounced than those of the calf-kidney polypeptide complex examined in the same experiment.
Peptide-DNA binding motifs (computational and cell-free)
A systematic survey of peptide-DNA complexes identified recurring structural motifs by which short peptides bind double-stranded DNA, giving a chemical framework for this peptide family.4
Gene-expression readouts (in vitro)
Reviews of the short-peptide literature summarise reported transcript-level changes in cultured cells after peptide exposure, stated as in vitro observations.5
Forms studied and handling
Supplied as a lyophilised powder in a sealed vial. Published handling practice for research peptides of this class is cold, dry, light-protected storage of the lyophilised solid, with reconstituted material kept refrigerated and used within the stability window established by the laboratory. For laboratory research use only.

Storage conditions at a glance
| Lyophilized, in transit | Stable for shipping for up to 3–4 months |
|---|---|
| Lyophilized, short term | Room temperature is usually adequate for several weeks; refrigeration under 4°C (39°F) is generally acceptable |
| Lyophilized, long term | Freezer at -80°C (-112°F) for several months to years |
| After reconstitution | Refrigerated; stable for up to 30 days |
| Light and moisture | Keep cold and away from light in the original sealed vial |
Why the powder is stable
All of our products are manufactured using the lyophilization (freeze drying) process, which keeps them stable for shipping for up to 3–4 months.
Lyophilization is a unique dehydration process, also known as cryodesiccation, where the peptides are frozen and then subjected to low pressure. This causes the water in the peptide vial to sublimate directly from solid to gas, leaving behind a stable, crystalline white structure known as lyophilized peptide. The puffy white powder can be stored at room temperature until it is reconstituted with bacteriostatic water.
Storing vials on arrival
Once peptides have been received, it is imperative that they are kept cold and away from light. If the peptides will be used in the next several days, weeks or months, short-term refrigeration under 4°C (39°F) is generally acceptable. Lyophilized peptides are usually stable at room temperatures for several weeks or more, so if they will be utilized within weeks or months such storage is typically adequate.
For longer term storage (several months to years) it is more preferable to store peptides in a freezer at -80°C (-112°F). When storing peptides for months or even years, freezing is optimal in order to preserve the peptide’s stability.
After reconstitution
Once the peptides are reconstituted with bacteriostatic water, they must be stored in the fridge to maintain stability. After reconstitution, the peptides will remain stable for up to 30 days.
