TB-500, also known as Thymosin Beta-4, is a synthetic 43-amino-acid peptide corresponding to the actin-sequestering protein thymosin beta-4, widely studied in tissue-repair research. It is supplied as a high-purity white lyophilized powder, >=99% by HPLC, in sealed vials for laboratory use. TB-500 is investigated in research on cell migration, angiogenesis, wound healing and regenerative processes, and is commonly applied in cell-culture and preclinical studies. The lyophilized format provides excellent stability and reproducible reconstitution for consistent experimental dosing. Each production batch is tested for purity and batch COA is issued upon request. Store the sealed vial at 2-8 degree C, protected from light and humidity; for extended storage -20 degree C is recommended with limited freeze-thaw cycles. Trial orders and bulk supply are both accepted, with OEM and private-label service and discreet neutral packing for worldwide shipping. Research use only, not for human or veterinary application.
