TB-500 is a synthetic peptide corresponding to the active, actin-binding region of Thymosin beta-4 (Tβ4), a naturally occurring regulatory protein. It is supplied as a lyophilized powder for laboratory use.
Research context
In published preclinical literature, Tβ4-derived peptides are studied in the context of actin regulation and cell-migration pathway research using in-vitro and tissue-model systems. Glow Peptides supplies TB-500 strictly as a reference material for such in-vitro and preclinical research. It is not a therapeutic product and is not for human or veterinary use.
Handling & storage
TB-500 is supplied lyophilized (freeze-dried). General laboratory handling practice for research materials of this type:
- Sealed vials: store lyophilized powder cold and away from light; long-term storage is typically in a freezer. Keep the vial sealed until the material is needed for analysis.
- Documentation: record the lot number and its Certificate of Analysis for your records.
Quality & testing
Check the lot documents shown for the selected material and match the report lot number to your label. Documentation may be missing or held for clarification. A document on file does not itself establish independent analytical review, identity, purity, or sterility.
