TB-500, also known as Thymosin Beta-4, is a synthetic 43-amino-acid peptide corresponding to the actin-binding protein thymosin beta-4. It is supplied as a high-purity lyophilized white powder (>=99% HPLC) in sealed vials for laboratory use. TB-500 is investigated in research on tissue repair, cell migration, angiogenesis and regenerative processes, and is frequently applied in cell-culture and preclinical studies. The stable freeze-dried presentation supports easy reconstitution and consistent dosing. Strict quality control is maintained across batches to ensure reproducible laboratory results. Every batch undergoes strict quality control, and a Certificate of Analysis (COA) is available for specific batches upon request to support reproducible laboratory work. For storage, keep the unopened reagent sealed at 2-8 degree C and protected from light and moisture; for long-term storage, store at -20 degree C and avoid repeated freeze-thaw cycles. We support both small trial orders and large-volume bulk orders. OEM and private-label packaging services are available for research projects, and secure neutral packing is used for all shipments with worldwide delivery to the USA, Europe, Canada, Australia, the UK and many other regions. Please note that this product is intended for laboratory research use only and is not for human or veterinary application.
