How to Reconstitute TB-500 (Thymosin Beta-4): A Step-by-Step Guide
Reconstituting TB-500 (Thymosin Beta-4) is not identical to reconstituting any other compound in this library. Highly water-soluble.
In plain English
Add bacteriostatic water gently down the vial wall; the powder is light and a direct stream can scatter it before it dissolves. It goes into solution easily. Portion it out the same day rather than repeatedly opening one vial, because every opening lets in fresh air.
What TB-500 (Thymosin Beta-4) actually is
TB-500 is a lab-made fragment of Thymosin Beta-4, a protein present in almost every cell in the body and especially concentrated in the fluid around a wound. Research on it centres on cell movement — the internal scaffolding that lets a cell change shape and travel where it is needed.
Supplied for laboratory research use only — not for human or animal use.
Third-party tested by HPLC and LC-MS, ≥99% purity, with a Certificate of Analysis on every order. Ships across Canada.

Diluent selection for TB-500 (Thymosin Beta-4)
Highly water-soluble. Thymosin beta family peptides are strongly hydrophilic and intrinsically disordered in free solution, adopting structure only on binding actin — there is no folded core to unfold and no hydrophobic surface to aggregate. Dissolution is rapid and complete in plain aqueous diluent.
Common reconstitution reference
A 10 mg vial in 2 mL yields 5 mg/mL. Aliquot promptly to limit repeated headspace exposure.
Open the TB-500 (Thymosin Beta-4) calculatorMethod notes for this compound
- Minimise headspace exposure — each opening introduces oxygen that drives methionine oxidation.
- Keep reconstituted vials out of direct light, including bench lighting over long sessions.
- Introduce diluent against the vial wall; the cake is light and can be dispersed by a direct stream before it dissolves.
What TB-500 (Thymosin Beta-4) is studied for
The defining studied mechanism: binding G-actin and influencing the polymerisation equilibrium that governs cell motility.
Investigated in models where directed cell movement into a tissue defect is the measured endpoint.
Two of the better-populated preclinical literatures for the parent protein.
Studied for effects on inflammatory signalling in tissue-injury models.
