What is TB-500 (Thymosin Beta-4 fragment)?

TB-500 is a synthetic analog of Thymosin Beta-4, one of the most widely referenced peptides in tissue and cellular biology research. Studied extensively for its role in actin regulation and cellular migration. 10mg lyophilized powder. Independently third-party tested to 99.6%+ purity. For in-vitro laboratory research use only. Not for human consumption.

Research Applications

Areas of investigation in the preclinical literature

Cytoskeletal
Actin-Binding Domain Research
The Ac-LKKTETQ motif corresponds to the actin-binding region of thymosin beta-4. It is examined in in-vitro studies of actin sequestration and cytoskeletal dynamics.
Vascular
Angiogenic Signaling Research
Investigated in preclinical and in-vitro models exploring endothelial cell behavior and angiogenesis-related signaling pathways.
Cellular
Cell Migration & Motility Research
Studied in in-vitro cell-culture systems examining cell migration, adhesion, and motility signaling mechanisms.
Extracellular Matrix
Matrix Signaling Research
Explored in preclinical models investigating cell-matrix interactions and extracellular-matrix signaling pathways.
Developmental
Progenitor Cell Signaling Research
Referenced in the preclinical literature within tissue-culture and animal-model studies of progenitor cell signaling and differentiation pathways.

Common Questions

What is this product used for?
This compound is supplied strictly for in-vitro laboratory research and scientific study by qualified researchers. It is not for human or veterinary use, consumption, or cosmetic application.
Who tests it and how do I verify purity?
Every batch is independently tested by Horizon Analytical (USA) — HPLC purity analysis and mass-spectrometry identity confirmation. The lot-matched Certificate of Analysis is published in our COA Library, and our results are cross-checked live by the independent watchdog PepAssure.
How is it stored and shipped?
The compound ships as a stable lyophilized powder that is room-temperature stable and does not require cold-chain shipping. Orders are dispatched within roughly 48 hours by UPS Ground in plain, unmarked packaging. We ship within the United States only.
What is used to reconstitute it?
Lyophilized research compounds are reconstituted with bacteriostatic water, which is sold separately. The reconstitution volume is determined by the researcher; we do not provide any protocol or dosing guidance.
Do you offer discounts for larger orders?
Yes. Order 2 items for 3.5% off, or 3 or more items for 5% off — the discount applies automatically at checkout and you can mix any compounds. Orders over $200 also ship free, and paying with crypto saves an additional 5%.
