TB-500 (a synthetic fragment of Thymosin Beta-4) is used in laboratory research to study actin-regulation, cell migration, and tissue-repair signaling pathways. 

The Certificates of Analysis (COAs) provided on this website are supplied by the manufacturer for the corresponding production batches. While we are actively transitioning to independent third-party verification, every batch is tracked through our internal quality system by manufacturer, production batch, purchase order, and individual kit when applicable to ensure complete traceability. 

We stand behind the quality of our research products and guarantee that all products meet our internal specifications of ≥99% purity and accurate labeled net content. Any product found not to meet these specifications will be addressed in accordance with our quality assurance procedures.
