TB-500 is a synthetic peptide corresponding to the actin-binding domain of Thymosin Beta-4, a 43-amino-acid protein expressed across most nucleated cell types. As a G-actin-sequestering peptide, it is used to study cytoskeletal dynamics underlying cell migration, proliferation, and differentiation. In-vitro and animal-model research examines its effects on endothelial cell migration, angiogenic signaling, and fibrosis-related gene expression, along with its anti-inflammatory activity and upregulation of cell-survival genes. Its low molecular weight and flexible structure make it a useful tool compound for studying peptide distribution through tissue. TB-500 is supplied as a lyophilized reference compound for cytoskeletal, vascular-biology, and tissue-remodeling research.
For laboratory and in-vitro research use only. Not for human or veterinary use.
Frequently Asked Questions
How does buy one, get one free work?
Every research compound on the site is BOGO. Add the quantity you want to pay for and we automatically double it — the free vials are the same size and the discount is applied at checkout with no code.
Are your products third-party tested?
Yes. Every batch is independently tested for identity and purity by HPLC and mass spectrometry at U.S. accredited labs, and a Certificate of Analysis is available for each batch.
What purity can I expect?
All compounds are 99%+ purity, verified by HPLC.
How should this be stored?
Store lyophilized (freeze-dried) material cool and dry; refrigerate once reconstituted at 2–8°C. Refer to the product details for compound-specific guidance.
How fast do you ship?
Orders dispatch within 24 hours Monday–Friday in temperature-controlled, tamper-evident packaging with tracking.
Are these for human use?
No. All products are sold strictly for in-vitro research and laboratory use only and are not for human or veterinary use.
