In short: TB-500 is a synthetic peptide related to Thymosin Beta-4 (TB4), studied in pre-clinical (in-vitro and animal) models of cell migration, angiogenesis and tissue repair. It is supplied strictly for laboratory research and is not approved for human use. For research buyers, the key purchasing criteria are verified purity (≥99% HPLC), confirmed identity (mass spectrometry) and batch traceability.
What is TB-500?
TB-500 is a research peptide based on the actin-binding region of Thymosin Beta-4, a naturally occurring protein involved in cytoskeletal organisation and tissue regeneration. The synthetic research compound is most commonly referenced by the active fragment sequence Ac-LKKTETQ. It is used as a research compound only and is not a medicine — it is not approved for therapeutic or human use.
What does the research investigate?
Published pre-clinical literature has examined TB-500 and Thymosin Beta-4 in models of cell migration, actin polymerisation, angiogenesis (new blood-vessel formation), and tissue remodelling across muscle, tendon, ligament, cardiac and neuronal tissue. Important: this research is largely in-vitro or in animals; findings in such models do not establish safety or efficacy in humans, and there are no controlled human clinical trials for TB-500. Always read the primary sources directly.
Purity and quality: what research buyers should check
For reproducible research, compound quality is everything:
- ≥99% purity by HPLC — confirm via the batch Certificate of Analysis.
- Identity by mass spectrometry — confirms the correct molecular weight.
- Batch numbering — traceability to a tested lot.
Vexar Lab supplies TB-500 as a pack of 10 vials, ≥99% HPLC-verified, batch-numbered, with mass-spec confirmation.
Handling and storage
Follow standard lyophilised-peptide practice: store sealed vials appropriately, reconstitute with the diluent specified by your method, and record batch numbers in your lab notes.

Frequently asked questions
Is TB-500 approved for human use?
No. It is a research compound supplied for in-vitro laboratory research only and is not approved for human consumption.
What is the difference between TB-500 and Thymosin Beta-4?
TB-500 is based on the active actin-binding fragment of the larger TB4 protein. Research literature often references both.
