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 how tissues recover after damage. 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.
