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. Every batch is quality-controlled and batch-specific COA can be supplied on request. Unopened product should be kept sealed at 2-8 degree C away from light and moisture, with -20 degree C recommended for long-term storage. We accept both trial and bulk orders, and OEM and private-label service is available. This peptide is for laboratory research use only, not for human or veterinary purposes.
