Mixing this vial? Calculate your unitsWhat is TB-500?
TB-500 is a synthetic fragment of thymosin beta-4: seven amino acids (Ac-LKKTETQ) from the actin-binding region of the 43-amino-acid protein. Researchers use it in actin and cell-migration studies, mostly in cell models.
This vial holds 5mg as a lyophilized powder. Each lot is HPLC and mass-spec tested, and the lot COA ships with your order. TB-500 is also one of the two peptides in the Wolverine Peptide Stack.
TB-500 Research Applications
Most published work uses full-length thymosin beta-4 rather than the TB-500 fragment:
- Actin binding and cytoskeleton studies in cell culture
- Cell-migration assays in cell models
- Detection methods for TB-500 in anti-doping testing
Note: TB-500 sold by CoreVionRX is intended strictly for research purposes. It is not intended for human consumption, diagnostic use, or therapeutic application.

TB-500 vs thymosin beta-4
Thymosin beta-4 is a 43-amino-acid protein (about 4,963 g/mol) that binds actin. TB-500 is the short synthetic fragment that covers its actin-binding region. The two names are often mixed up, so the molecular mass on the lot COA is the quickest way to tell which compound a vial holds.
What published studies examined
- Actin binding and cytoskeleton studies in cell culture, mostly with full-length thymosin beta-4
- Cell-migration assays in cell models
- Methods for detecting TB-500 and its breakdown products in anti-doping testing
Published work on the TB-500 fragment itself is limited, and human data are lacking. TB-500 is on the World Anti-Doping Agency (WADA) prohibited list.
Verified before it ships
Every lot is tested by an independent lab before it reaches our shelf: HPLC for purity and mass spectrometry for identity. The lot-specific Certificate of Analysis ships with your order, so you can match the number on your vial to the data.
Storage
- Sealed vial: store frozen at -20°C, away from light and moisture.
- Once dissolved for lab work: keep refrigerated at 2–8°C.

Frequently Asked Questions About TB-500
Common questions from researchers buying TB-500 for laboratory studies.
What is TB-500?
TB-500 is a synthetic seven-amino-acid fragment of thymosin beta-4 (residues 17–23, Ac-Leu-Lys-Lys-Thr-Glu-Thr-Gln), the actin-binding region of the full protein.
What is in the TB-500 5mg vial?
One sealed glass vial holding 5mg of TB-500 as a lyophilized powder. Formula C38H68N10O14, molecular weight 889.0 g/mol, CAS 885340-08-9.
Is TB-500 the same as thymosin beta-4?
No. Thymosin beta-4 is the full 43-amino-acid protein (about 4,963 g/mol). TB-500 is a short synthetic fragment of it. The molecular mass on the lot COA shows which compound a vial holds.
How should TB-500 5mg be stored?
Keep the sealed vial frozen at -20°C, away from light and moisture. Once the powder is dissolved for lab work, keep the solution refrigerated at 2–8°C.
