TB-500 is a synthetic fragment of Thymosin Beta-4 studied for actin regulation, cell migration, and tissue-repair research.

TB-500 (Thymosin Beta-4 Fragment)

  • Synthetic peptide based on the active region of Thymosin Beta-4

    Interacts with the cytoskeletal protein actin

  • Studied for cell migration, angiogenesis, and tissue repair

    Investigated for flexibility and recovery in models

  • Frequently paired with BPC-157 in tissue-repair research

Research Use Notes

  • Supplied as lyophilized powder

    Requires reconstitution before use

  • Research Water required for mixing (sold separately)

    Swirl gently, never shake

Storage

  • Store lyophilized vial frozen for long-term holding

  • Keep reconstituted solution at 2 to 8°C

    Protect from light and heat

Handling

  • Maintain sterile technique throughout reconstitution

    For laboratory research use only

  • Avoid repeated freeze-thaw cycles to preserve integrity
