- Investigated in angiogenesis research
- Research Grade purity >=98%
TB-500 is the synthetic form of thymosin beta-4 (Tb4), a 43 amino acid actin-sequestering protein found abundantly in mammalian cells and highly conserved across species. It is supplied as the full-length, N-terminally acetylated 43-residue sequence, which contains the LKKTETQ actin-binding motif at residues 17-23 that mediates much of its biological activity. Research has examined its role in cell migration, proliferation, and differentiation; angiogenesis and new blood-vessel formation; inflammation modulation; and tissue repair across multiple organ systems including musculoskeletal tissue, cardiac muscle, the cornea, and skin. Supplied as a lyophilised white powder with a molecular weight of 4963.4 Da and molecular formula C212H350N56O78S. Supplied strictly for in-vitro laboratory research. Not for human or veterinary consumption.
Frequently Asked Questions
Is TB-500 legal to buy in Australia?
TB-500 is supplied strictly as a research chemical for in-vitro laboratory use. It is not approved for human therapeutic use in Australia and is not for human or animal consumption. Researchers are responsible for compliance with Therapeutic Goods Administration (TGA) regulations and their institution's protocols.
Is TB-500 third-party tested?
Yes. TB-500 is independently verified by Ozcanium Analytics, an independent Australian laboratory, at 98.00% purity by UPLC-MS/MS, analysed 27 August 2026 on lot APL-TB10-2608-01, net content 9.73 mg, verification code OZ-HPLCMS-MJ39. The report is published in full on this page, and the verification code can be redeemed in the laboratory's own portal, so the document is confirmed against their records rather than ours. Every batch is also analysed in-house by HPLC and mass spectrometry and ships with a batch-specific Certificate of Analysis.
What purity is TB-500?
TB-500 is independently verified by Ozcanium Analytics at 98.00% purity by UPLC-MS/MS, analysed 27 August 2026. We specify ≥98% purity — the High-Tier Research Grade (commercial RUO) standard — and every batch is also analysed in-house by HPLC and mass spectrometry and ships with a batch-specific Certificate of Analysis.
Does TB-500 ship with a Certificate of Analysis (COA)?
Yes — every batch ships with a batch-specific COA documenting HPLC purity and mass-spectrometry identity. 5 TB-500 batch certificates are published in full at australianpeptidelabs.com.au/certificates/tb-500, so the analysis can be read before ordering and the batch number printed on the vial matched against it.
Where can I buy TB-500 in Australia?
TB-500 can be ordered here from Australian Peptide Labs for in-vitro research use, dispatched same day from within Australia with a COA included.
Do you provide dosing or administration guidance for TB-500?
No. As these compounds are supplied for laboratory research only, we do not provide dosing or administration protocols. Our research library covers reconstitution and concentration calculations for in-vitro work.
