Research context
TB-500 is a research peptide based on a fragment of Thymosin Beta-4, a 43-amino-acid protein. As a laboratory reagent it is studied for actin-binding behavior and stability characteristics in in-vitro systems.
The preclinical scientific literature on Thymosin Beta-4 and related fragments spans cell-biology and animal-model research. All such work is experimental; TB-500 is not an approved human therapeutic.
DMV Research supplies TB-500 with a third-party Certificate of Analysis per batch, confirming identity and purity for research applications.
Frequently asked questions
What is TB-500?+
TB-500 is a synthetic peptide corresponding to an active fragment of Thymosin Beta-4 (Tβ4), used as a research reference compound. CAS 77591-33-4.
Is TB-500 approved for human use?+
No. TB-500 is not approved for human use by any regulatory agency. It is supplied for laboratory and research purposes only.
