Overview
Sigumir is the cartilage-directed member of the Cytomax series of peptide bioregulators developed at the St Petersburg Institute of Bioregulation and Gerontology under Vladimir Khavinson. Unlike a synthetic peptide with a single defined sequence, the Cytomax preparations are low-molecular-weight peptide complexes extracted from a specific tissue of young animals — in this case cartilage and connective tissue — then fractionated and dried. The product is therefore a characterised mixture rather than one molecule, which is why no single CAS number, formula or sequence can be assigned to it.
The organising idea behind the bioregulator programme is tissue specificity: the hypothesis that short peptide fractions derived from a given tissue interact preferentially with cells of that same tissue, influencing gene expression and protein synthesis. Khavinson's group has published on this concept for several decades, including work on peptide–DNA interaction, and it has also produced defined synthetic analogues for individual tissues — Cartalax (Ala-Glu-Asp-Gly) is the short synthetic counterpart most often discussed alongside Sigumir in the cartilage context.

Questions about Sigumir (Cartilage Bioregulator)
What is Sigumir made from?
It is a low-molecular-weight peptide complex extracted from cartilage and connective tissue of young animals, then fractionated and dried. It is a characterised mixture defined by source tissue and fraction size, not a synthetic peptide with one sequence, which is why no single formula or CAS number is listed.
How does it differ from Cartalax?
Cartalax is a defined synthetic tetrapeptide, Ala-Glu-Asp-Gly, that can be characterised precisely by HPLC and mass spectrometry. Sigumir is the natural extract fraction for the same tissue. Comparative studies often run both, since a mixture cannot support the same structural claims as a single sequence.
Is any documentation supplied?
Each lot ships with the available certificate of analysis and pack labelling stating peptide content. Because the article is a fraction rather than a single molecule, that documentation covers batch identity, source designation and fraction characteristics rather than a single-compound purity figure.
Is it approved for medical use?
No. Sigumir is not approved as a drug by the FDA, EMA or comparable regulators, and it is not sold here as a supplement or medicine. It is listed as a research article for laboratory investigation only, and no intake or dosing guidance is provided with it.
How should it be stored?
Keep the pack sealed at room temperature or cooler, protected from light, heat and humidity. Dried peptide fractions are hygroscopic, so moisture exclusion matters. Log the lot number and receipt date and retain a reference sample, since composition can vary between batches of a tissue-derived preparation.
