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.

Storage & Handling

Storage: Keep lyophilized research vials sealed and protected from heat, moisture, and direct light. Freezer storage at -20°C is recommended for unopened vials intended for longer-term retention.
