TB-500
Tissue-repair peptide
TB-500 is a lab-made peptide built to match a key active part of Thymosin Beta-4, a protein found naturally in many of the body's cells. It copies the section of that protein most studied in the lab.
Also known as TB-500 · Thymosin Beta-4 fragment · TB4 fragment
How it is studied
Researchers describe it as an actin-binding peptide, which means it grabs onto actin — one of the structural proteins cells use to change shape and move. In animal and cell studies, this activity is looked at alongside the forming of new blood vessels and the movement of cells.
Research context
A reference compound in early connective-tissue research models, where scientists study how cells move and how new blood vessels form in lab studies.
Good to know
Findings are mostly early-stage animal and cell research. Research use only.
Research area
Tissue-repair research. This group covers peptides that scientists study in the lab to learn how cells and connective tissue behave in controlled models. In cell samples and animal studies, researchers use them to explore cell movement, new-vessel formation, and inflammation-signaling. All are research compounds for laboratory use only, with no established use in people.
