What Does TB-500 (Thymosin Beta-4) Dissolve In? Solvents Explained
Solubility behaviour is where compounds in this library differ most sharply from one another. For TB-500 (Thymosin Beta-4), the determining factors are structural: synthetic fragment of thymosin beta-4.
In plain English
Very water-friendly. It has no fixed shape and no greasy region, so there is nothing to resist dissolving. Its difficulty is chemical rather than physical — it dissolves happily, then slowly reacts with oxygen. That is the opposite problem to something like IGF-1 LR3.
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.
Technical detail below
How TB-500 (Thymosin Beta-4) behaves in solution
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.
Readily worked at 2–5 mg/mL.

Structural basis
TB-500 (Thymosin Beta-4) is synthetic fragment of thymosin beta-4. TB-500 corresponds to the active region of Thymosin Beta-4, a 43-residue actin-sequestering protein present in virtually every mammalian cell type and abundant in wound fluid and platelets. Research interest followed the observation that the protein's activity in tissue-organisation models is largely retained by a short fragment of it.
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.
