Research background

TB-500 is a synthetic version of Thymosin Beta-4, a naturally occurring peptide present in virtually all human and animal cells. It plays a critical role in the building of new blood vessels, muscle tissue fibres, cell migration and blood cell reproduction.

Research has focused on its role in wound healing, inflammation modulation, and muscle fibre repair. It has been studied in models of cardiac repair, eye injury, and skin wound healing.

Reconstitution

  • Supplied as a lyophilized (freeze-dried) powder for laboratory reconstitution.
  • Bacteriostatic water (0.9% benzyl alcohol) is the most common reconstitution solvent for multi-use research handling; sterile or acetic-acid solutions are used for specific compounds.
  • Introduce solvent slowly against the vial wall rather than directly onto the powder, and allow it to dissolve without vigorous shaking.
  • Use the reconstitution calculator to determine solvent volume for a target concentration in your protocol.

Storage & handling

  • Lyophilized powder: store sealed at -20 °C for long-term stability; short periods at 2–8 °C are generally acceptable.
  • Once reconstituted: refrigerate at 2–8 °C and protect from light; use within the compound-specific window noted on the COA.
  • Avoid repeated freeze–thaw cycles of reconstituted solution.
  • Keep away from direct light and heat at all times.

Purity & verification

Every Popular Peptides batch is third-party tested by HPLC and LC-MS with a published Certificate of Analysis (≥99% purity).
