Product Description:

TB-500 is a synthetic peptide corresponding to the Thymosin Beta-4 protein. It consists of 43 amino acids in its native form; TB-500 represents a truncated sequence designed for experimental and analytical research applications. In laboratory settings, TB-500 is studied for its biochemical properties and peptide behavior under controlled conditions. This product is supplied as a pre-formulated aqueous research solution to support consistency in experimental workflows.

Research Applications:

• Investigation of actin-associated peptide interactions in vitro
• Study of intracellular structural interactions and peptide transport mechanisms
• Evaluation of peptide stability in aqueous environments
• Comparative analysis of thymic peptide fragments in laboratory models

Storage and Handling:

• For optimal stability, store sealed product in a cool, dark, and dry environment. Refrigeration at 2–8 °C is recommended after first puncture or once the seal has been compromised
• Do not freeze
• Protect from light
• Handle under aseptic laboratory conditions

Product Specifications:

• Formulation: Aqueous solution
• Concentration: 1 mg/mL
• Total Content: 30 mg per bottle
• Delivery Format: Metered liquid solution
• Dispenses per Container: ~200
• Amount per Dispense: ~150 mcg
• Analytical Approach to Finished Formulations: Purity is a metric used for isolated raw materials, such as lyophilized peptide powders. Finished formulations—such as capsules, liquids, and topicals—contain multiple components, including excipients and stabilizers. In these systems, a single purity value does not accurately represent the overall composition. Instead, identity and assay (content) are reported on the COA to confirm the presence of the correct compound and to verify that the labeled amount per unit is accurate. This approach reflects standard analytical practice and provides more meaningful information for research applications
