Brief Description

Synthetic thymosin beta-4 acetate research peptide studied in actin regulation, cellular migration, angiogenesis, and tissue remodeling. For research use only — not for human consumption.

Research Context

Actin Regulation and Cell MigrationResearch has examined thymosin β4 in connection with actin dynamics, cellular migration, angiogenesis, and tissue remodeling processes. These pathways are often discussed in experimental models focused on repair signaling and cell movement.

TB-500 / Thymosin β4 Naming

TB-500 is commonly used as a catalog name in the research peptide market. This product is identified as full-length thymosin β4 acetate — a 43-amino-acid peptide with molecular weight 4963.44 Da — rather than a separately identified shorter TB-500 fragment.

Batch COA/testing documentation is used to verify the material identity.
