TB-500 (Thymosin Beta-4 Fragment) for In Vitro Studies

TB-500 is a research peptide corresponding to a region of thymosin beta-4, a naturally occurring 43-amino-acid protein involved in actin binding and cell migration. Preclinical studies have explored its role in wound-healing models and cytoskeletal dynamics — exclusively in non-clinical research contexts.

Naming and catalogue clarity

Literature and suppliers use several names — TB-500, thymosin β-4 fragment, and vendor-specific codes. Always match catalogue numbers and sequences against your protocol requirements. The COA identity test confirms the expected mass.

Reconstitution example

A 5 mg lyophilised vial reconstituted with 2 mL diluent gives 2.5 mg/mL. For a planned 500 mcg (0.5 mg) research sample, the draw volume is 0.2 mL on a U-100 syringe — 20 graduated units. Adjust volumes with our calculator before preparing working stocks.

Storage and stability

• Lyophilised: prefer −20 °C for extended storage.
• In solution: refrigerate at 2–8 °C and use within the window validated by your lab.
• Minimise freeze-thaw cycles by aliquoting working volumes.
