TB-500

TB-500 is a synthetic peptide corresponding to the active region of Thymosin Beta-4, a naturally-occurring actin-binding protein, studied in cytoskeletal-dynamics and cell-migration research.

TB-500/Thymosin Beta-4 research has examined actin-sequestration dynamics and their downstream effects on fibroblast and endothelial cell migration in in-vitro wound-model assays.

• BPC-157 — a related compound frequently studied alongside TB-500 (Thymosin β4 fragment) in comparative research designs.

For in-vitro assay preparation, researchers calculate a target concentration (mg/mL) from the vial's labeled mass and the volume of sterile diluent added, then aliquot and store per standard laboratory cold-chain practice. This is a laboratory dilution calculation only, performed strictly for analytical or in-vitro research purposes. Not for use in humans or animals.

Lyophilized powder should be stored at -20°C for long-term stability, or refrigerated (2-8°C) for short-term use, protected from light and moisture. Once reconstituted for laboratory use, follow standard cold-chain handling and use within the timeframe indicated by your institution's protocols.

TB-500 (Thymosin β4 fragment) ships with a QR-linked, batch-specific certificate of analysis (COA) confirming identity and purity via HPLC. Researchers should always confirm the lot number on their vial matches the COA on file before beginning any assay.

This reference material is manufactured and quality-tested to support reproducible research outcomes. Every batch is independently verified before it ships, and COAs remain accessible for future reference.
