TB-500
What TB-500 is studied for.
Thymosin β4 fragment. Investigated across the following preclinical and in-vitro research areas.
Cardiac repair
Studied in preclinical and in-vitro research for cardiac-tissue repair.
Tissue regeneration
Studied in preclinical and in-vitro research for tissue regeneration and recovery.
Wound healing
Studied in preclinical and in-vitro research for wound healing and anti-inflammatory response.
Hair growth

The science behind TB-500
TB-500 is a synthetic fragment of Thymosin β4, an actin-sequestering protein (ACTA/ACTB/ACTG family). Research has examined its role in cell migration, angiogenesis and tissue regeneration across cardiac, wound-healing and connective-tissue models.

Reconstitution & storage.
General laboratory handling reference for lyophilized peptides. Always follow your institution's protocols.
Equilibrate
Let the sealed vial reach room temperature before opening to prevent condensation.
Add solvent
Slowly add bacteriostatic water down the vial wall — never directly onto the powder.
Dissolve gently
Swirl, don't shake. Let it go fully clear; avoid foaming or vortexing.
Store cold
Refrigerate the reconstituted solution at 2–8°C; minimize freeze-thaw cycles.
Concentration (mg/mL) = vial mass (mg) ÷ solvent added (mL). Use this to plan your working dilutions for in-vitro research.
10 mg ÷ 5 mL = 2 mg/mL
Risk stays with us, not you.
