Description
What is TB-500?
TB-500 is a thymosin beta-4–related research peptide commonly used in models of actin-binding biology, cell motility, cytoskeletal remodeling, and tissue-remodeling endpoints.
Commercial TB-500 identity can vary by supplier and fragment designation; researchers should confirm sequence and identity against the batch COA before use.
Mechanism of Action / Research Focus
Research interest in TB-500 centers on thymosin beta-4 biology and actin-associated cellular processes. These pathways are relevant to cell migration, cytoskeletal organization, endothelial models, and tissue-remodeling endpoints.
As with all fragment-based research peptides, the exact sequence and salt form should be verified before experimental comparison across vendors or studies.
Common Research Applications

Certificate of Analysis (COA)
Applicable lots should be supported by batch-specific analytical documentation. Before beginning work, verify product identity, purity, fill amount, lot number, and storage requirements against the COA and product label.
TB-500 FAQs
Is TB-500 the same as full-length thymosin beta-4?
Commercial TB-500 is commonly described as a thymosin beta-4–related research peptide or fragment; verify exact identity on the COA.
What should be verified before use?
Confirm sequence, fill amount, lot number, COA, and storage conditions.
Is this for human use?
No. It is strictly for laboratory research use.
