Actin binding. Cell movement. A focused research model.
Thymosin beta-4 is studied as an actin-monomer-binding peptide. The literature below describes experimental models and does not provide clinical or veterinary guidance.
-
G-actin binding
Thymosin beta-4 binds monomeric actin and helps regulate the pool available for filament assembly.
-
Cytoskeletal dynamics
Its actin interaction is studied in models of cytoskeletal organization and remodeling.
-
Cell migration
Published studies examine thymosin beta-4 in endothelial and other cell-migration models.
-
Angiogenic signaling
Research has evaluated actin-binding regions and signaling pathways associated with angiogenic responses.

Common questions
Research context, batch testing, storage and verification for TB-500 10mg.
What is TB-500 10mg?
On this product page, TB-500 denotes synthetic thymosin beta-4 identified by CAS 77591-33-4. Thymosin beta-4 is a 43-amino-acid actin-monomer-binding peptide. The vial contains lyophilized research material and is supplied strictly for in-vitro laboratory use.
Is this a short fragment of thymosin beta-4?
No. This product is full-length synthetic thymosin beta-4, CAS 77591-33-4.
How is thymosin beta-4 studied in relation to actin?
Thymosin beta-4 binds monomeric G-actin and is studied for its role in maintaining the actin pool used during cytoskeletal assembly and remodeling. Published work also examines related effects in cell-migration models.
What research areas are associated with thymosin beta-4?
Peer-reviewed studies investigate thymosin beta-4 in actin dynamics, endothelial-cell migration, angiogenic signaling and tissue-repair models. These research contexts do not establish a medical, therapeutic or veterinary use for this product.
How does TB-500 differ from BPC-157?
They are distinct research compounds with different structures and literature bases. This TB-500 listing corresponds to synthetic thymosin beta-4 and its actin-related biology; BPC-157 is a separate peptide studied in other experimental pathways. No combination or equivalence is implied.
How does Prime Peptides test TB-500?
Every batch goes through three layers of quality control. Our manufacturer runs its own QC and has its production independently tested by Janoshik Analytical. Then Vanguard or Janoshik tests every batch we stock again, for identity, HPLC purity, net content and endotoxins before we approve it for sale.
Every approved batch has its lab report on the Test Results page.
What purity standard does Prime Peptides use?
We target 99%+ purity by HPLC. The actual purity of each batch is measured independently and published in its lab report, so you can check the result yourself.
How should TB-500 research material be stored?
Store the sealed lyophilized vial at -20°C, protected from light, and follow the product label and batch documentation. After reconstitution, use controlled refrigerated laboratory storage at 2-8°C within the defined research window and avoid repeated freeze-thaw cycles.
