Compound Class: Synthetic peptide (Thymosin Beta-4)
TB-500 is a synthetic peptide consisting of a defined amino acid sequence corresponding to Thymosin Beta-4. This product is supplied in an encapsulated solid format to support controlled storage, handling, and measurement within laboratory research environments. The encapsulated format serves solely as a physical containment and presentation method and does not imply any route of administration. TB-500 (Tβ-4) is intended exclusively for controlled in-vitro laboratory research conducted by qualified professionals investigating peptide structure, stability, and interaction models.
In-vitro evaluation of peptide–actin interaction models
Laboratory investigation of synthetic Tβ-4 behavior
Studies focused on peptide stability and degradation characteristics
Comparative analysis of full-length thymosin peptides versus fragment analogues
Store in a cool, dry environment away from direct light
Maintain container tightly sealed when not in use
Handle using appropriate laboratory safety and aseptic techniques
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.
Format: Encapsulated solid research peptide
Appearance: White to off-white solid
Solubility: Soluble in aqueous laboratory media following capsule removal for analytical use
