TB-500 Thymosin Beta-4

For in vitro research use only. TB-500 is not for human or veterinary consumption, diagnosis, treatment, or prevention of any condition.

TB-500 is a synthetic version of Thymosin Beta-4, a protein found naturally in mammalian tissue. Preclinical studies have investigated how it interacts with actin — a structural protein that controls how cells move and organise themselves, particularly during tissue repair.

Research overview

TB-500 is a synthetic version of Thymosin Beta-4 — a protein found naturally in mammalian tissue. Preclinical studies have investigated its role in regulating actin — a structural protein that works a bit like scaffolding inside cells, controlling how they move, divide, and organise themselves during repair. Animal studies have examined its effects on connective tissue response (how the body's supporting tissues react to damage), the migration of repair cells to injury sites, and cardiac tissue (heart muscle) following experimentally induced damage. For research use only. Not for human or veterinary consumption.

Summary paraphrased from the peer-reviewed preclinical literature. Full citations will be available in the research library. For in vitro research use only.
