TB-500 is a synthetic peptide corresponding to the active region of Thymosin Beta‑4 (TB4), a naturally occurring 43‑amino acid peptide found in virtually all human and animal cells. TB-500 represents the 17‑amino acid N‑terminal fragment (also referred to as the “actin‑binding domain”), which is responsible for many of TB4’s characterized biochemical properties. This 10mg format is supplied as a lyophilized (freeze‑dried) powder for reconstitution and use in in‑vitro laboratory applications.
