TB-500 is a synthetic peptide corresponding to the active, actin-binding region of Thymosin beta-4 (Tβ4), a naturally occurring regulatory protein. It is supplied as a lyophilized powder for laboratory use.
Research context
In published preclinical literature, Tβ4-derived peptides are studied in the context of actin regulation and cell-migration pathway research using in-vitro and tissue-model systems. Glow Peptides supplies TB-500 strictly as a reference material for such in-vitro and preclinical research. It is not a therapeutic product and is not for human or veterinary use.
Handling & storage
TB-500 is supplied lyophilized (freeze-dried). General laboratory handling practice for research materials of this type:
- Sealed vials: store lyophilized powder cold and away from light; long-term storage is typically in a freezer. Keep the vial sealed until the material is needed for analysis.
- Documentation: record the lot number and its Certificate of Analysis for your records.
Quality & testing
Every lot of TB-500 we supply is independently tested at a U.S. laboratory and ships with a lot-specific Certificate of Analysis. Testing includes HPLC with UV detection for purity and mass spectrometry for identity, with our purity standard at ≥99.2%.
You can search any lot and view its documentation on our Quality & COA verification page, and learn what the numbers mean in how to read a Certificate of Analysis. Our published customer rating is 4.5 on Trustpilot.
TB-500 is available as an independently tested, ≥99.2%-purity research reference material with a per-lot Certificate of Analysis.
