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. The thymosin beta-4 fragment is studied for its role in actin regulation, cell migration and tissue-remodeling responses after injury. Investigators frequently combine it with repair-focused peptides in recovery protocols and examine angiogenic endpoints. The peptide is provided as a lyophilized powder in sealed vials, with lot-specific purity data and flexible pack options. Inventory is managed to ensure prompt dispatch for frequently ordered items, and production capacity supports both small and large quantities. Shipping is arranged worldwide with secure, discreet packaging, and every parcel is trackable. We maintain open communication from quotation to delivery confirmation, keeping buyers informed at each stage.
