Cartalax is a synthetic tripeptide with the amino acid sequence Ala-Glu-Asp (also designated as AED or T-31) from the class of short peptide bioregulators, developed within the research school of Professor Vladimir Khavinson. In scientific research, Cartalax is studied as a model compound in cell models for cartilage and connective tissue, particularly chondrocytes (cartilage cells) and fibroblasts (connective tissue cells). It is offered as a freeze-dried powder (lyophilized powder) with a controlled purity of at least 99% (HPLC) and is intended exclusively for laboratory and research purposes.<\/p>\n
Cartalax belongs to the short peptide bioregulators: a family of very short, defined peptide sequences described in the Russian peptide literature and catalogued according to the tissue type to which they are coupled in model studies. The molecule is composed of three amino acids\u2014alanine, glutamic acid, and aspartic acid\u2014which are linked via two peptide bonds to form a structurally precisely defined tripeptide with a molecular weight of approximately 333 Da.<\/p>\n
Due to their small size, short peptide bioregulators are investigated in the scientific literature as model compounds that may interact with regulatory sequences and the expression of tissue-specific genes in cultured cells. In this context, Cartalax is classified among the bioregulators related to cartilage and connective tissue, thereby serving as a standardized tool for modeling gene expression and cellular dynamics in controlled in vitro systems. The compound is a tool for fundamental research and not a therapeutic or consumer product.<\/p>\n
In a laboratory context, Cartalax is used in the following research areas, among others:<\/p>\n
Cartalax is part of a broader group of short peptide bioregulators, each of which has its own amino acid sequence and associated tissue model system. While Cartalax (Ala-Glu-Asp) is linked to cartilage and connective tissue models in the literature, other members of this family are related to other cell types. The tripeptide Pinealon 20mg<\/a> (Glu-Asp-Arg), for example, is studied as a model compound in neuronal cell models, while the dipeptide Vilon 20mg<\/a> (Lys-Glu) and Crystagen 20mg<\/a> are being investigated in yet other tissue-specific systems. Additionally, for research focusing on the extracellular matrix and collagen models, the matrikine peptide is used. Matrixyl 10 mg<\/a> a related reference point. This mutual comparison makes the bioregulator family suitable for systematic, sequence-directed in vitro research.<\/p>\nSpecifications<\/h2>\n

In a laboratory setup, the lyophilisate is reconstituted prior to analysis; for short peptides, bacteriostatic water is typically used for this purpose. The freeze-dried powder remains most stable when stored refrigerated and in the dark, protected from light and moisture. After reconstitution, the solution is kept refrigerated (2\u20138 \u00b0C) and protected from repeated temperature fluctuations to maintain the conformational integrity of the peptide. Work with clean, calibrated materials to avoid cross-contamination in analyses.<\/p>\n Want to know more?<\/strong> Read our guide: Bacteriostatic water: what is it used for and how do you mix it correctly?<\/a><\/p>\n |
