Synthetic fragment of Thymosin Beta-4, an actin-regulating protein occurring naturally in almost all human tissues. Studied for its role in tissue regeneration, cell migration and angiogenesis.

What is TB-500? Mechanism of action

TB-500 is a synthetic fragment of thymosin beta-4, a protein found naturally in almost all human cells and in wound fluid. The fragment covers the active region the literature refers to as the actin-binding sequence.

In searches and on supplier listings the same fragment appears as TB500, TB 500 and — incorrectly but commonly — T-500. All refer to the thymosin beta-4 fragment.

Thymosin beta-4 is one of the principal actin-binding proteins in the cell. Actin is the structural protein that determines cell shape and cell migration, and it is that migration which connects research on this molecule to tissue repair: cells moving toward a damaged area do so by rearranging their actin skeleton.

Published work spans cell culture, animal models and a small number of early clinical studies. TB-500 itself holds no marketing authorisation anywhere and has been on the World Anti-Doping Agency prohibited list since 2011.

We supply it as a lyophilised powder, solely as laboratory material for in-vitro research.

Research areas

The areas below recur in the published literature on this peptide. They are directions of research, not applications — no statement is made about efficacy or suitability for any use.

  • Tissue repair and regeneration
  • Wound healing and cell migration
  • Angiogenesis stimulation
  • Inflammation modulation

Buying TB-500 for research

TB-500 is only as useful as research material as the documentation that comes with it. This is what we record per batch:

  • Every batch is analysed by HPLC. The purity figure and its lot number appear on this page and on the label.
  • The lot number on the vial matches the certificate of analysis, so the measurement traces back to the vial you receive.
  • Supplied as a lyophilised powder rather than a solution — the form that best survives transport and storage.
  • For analytical and preclinical laboratory research only. Not for human or animal consumption.

Reconstitution and storage

Lyophilised and unopened, the peptide is kept cool, dry and dark. Brief exposure to room temperature in transit is normal for the powder, and is precisely why it ships in this form.

The literature generally uses bacteriostatic water for reconstitution. Once reconstituted the solution has a limited shelf life and belongs in refrigerated storage. Exact conditions vary by protocol; we prescribe none.

Frequently asked questions

What does TB-500 cost?
TB-500 costs € 59,95 for 10 mg. Ordering multiple vials applies a volume discount automatically.
Can I order TB-500 in the Netherlands?
Yes. We ship from the Netherlands, discreetly and neutrally packaged, with track and trace. Within the Netherlands and Belgium delivery normally takes 1–2 working days after processing, elsewhere in the EU 2–5 working days. Payment is by iDEAL and shipping is free from €75.
Do I get a certificate of analysis with TB-500?
Yes. The current lot is PL-2708 with a measured purity of ≥ 99.1% HPLC. The lot number on the vial matches the certificate of analysis, so the measurement traces back to the vial you receive.
How do I store TB-500?
Unopened, TB-500 is kept at −20 °C, dry and dark. It ships as Lyophilised powder; in that form it withstands transport. Once reconstituted the solution has a limited shelf life and belongs in refrigerated storage.
What is TB-500 intended for?
In-vitro laboratory research only. TB-500 is not intended for human or animal consumption, not for diagnostic use, and not for any therapeutic application. We provide no dosing and no administration guidance.
