Description

Research Use Only. This material is supplied for in-vitro laboratory research by qualified professionals. It is not a medicine, supplement, cosmetic ingredient or veterinary product, and it is not for human or animal consumption. The research summary below describes published scientific literature; it is not a claim of effect, benefit or suitability for any person.

TB-500 is a lab-made version of Thymosin Beta-4, a peptide found naturally in almost every type of tissue. Known primarily as an actin-sequestering molecule, it is tied to core processes such as how cells move, how new blood vessels develop, and tissue-repair processes studied in animal models. Supplied as lyophilised material for in-vitro laboratory research.

Research context

Published studies that mention or investigate TB-500 show up across several areas, including tissue repair models, cardiovascular marker work, actin regulation, inflammatory signaling, neurological model research, and ocular tissue models.

The product is intended for scientific research and development purposes only. Chemical substances shall not be used as a drug, medicine, active substance, medical aid, cosmetic product, a substance for production of a cosmetic product neither for human consumption that is any food or food supplement or otherwise similarly used on humans or animals. Intended only for in-vitro research, such as Receptor-ligand binding studies, Enzyme activity assays, Cell proliferation assays, Cell signaling assays, Epitope mapping, etc. Do not order for personal use, clinical use, injection, compounding, resale as a supplement, or any project that requires a specific assay not shown for the relevant batch.
