TB-500 Research Profile

TB-500 is a synthetic version of the naturally occurring peptide Thymosin Beta-4, a 43-amino-acid protein found in high concentrations in blood platelets and wound fluid. Preclinical research has investigated its role in actin regulation, cell migration, angiogenesis, and tissue repair processes. Studies have examined its effects in models of cardiac injury, tendon damage, and corneal wound healing. TB-500 is for research use only and is not approved for human therapeutic application.

Frequently Asked Questions

Q: What makes TB-500 different from BPC-157 in research?
A: While both peptides are studied in tissue repair contexts, TB-500 primarily works through actin sequestration and promotion of cell migration, whereas BPC-157 is associated with angiogenic and cytoprotective mechanisms. Many research protocols examine them independently or in combination to assess complementary effects.

Q: What is the stability of TB-500 in lyophilized form?
A: Lyophilized TB-500 stored at 2-8°C maintains stability for up to 24 months. Avoid repeated freeze-thaw cycles to preserve structural integrity. Once reconstituted, use within 30 days and keep refrigerated at all times.

Q: Is a certificate of analysis available for TB-500?
A: Yes. Official Peptides provides third-party HPLC and mass spectrometry verification for every TB-500 batch. COAs are available upon request or can be included with your shipment.
