TB500 is a synthetic peptide fragment derived from Thymosin Beta?4, an endogenous polypeptide widely present in mammalian tissues. It retains the key bioactive domain responsible for modulating cell migration and tissue remodeling, making it a core research reagent for studying wound healing and tissue regeneration mechanisms. Unlike the full-length Thymosin Beta?4 molecule, TB500 features a shorter amino acid sequence, which brings better stability and lower production cost for laboratory research applications.

In biological research models, TB500 acts on actin regulation pathways. It can promote the migration of endothelial cells and fibroblasts, support angiogenesis, and modulate local inflammatory responses during tissue recovery processes. Researchers commonly deploy TB500 in cell culture and animal model experiments to explore its effects on soft tissue injury recovery, tendon and ligament repair, as well as inflammation regulation. It does not trigger strong systemic hormonal responses, which helps reduce confounding variables in experimental design.

Our TB500 is produced via solid-phase peptide synthesis, followed by multi-step chromatographic purification. Each batch undergoes strict quality screening to remove truncated peptide impurities, coupling residues and heavy metal contaminants. Mass spectrometry confirms the molecular weight matches the theoretical value, while HPLC verifies high purity, ensuring reproducible experimental data across different research groups. The lyophilized formulation locks up bioactivity during shipment and long-term storage.

Once reconstituted, the peptide solution is sensitive to temperature fluctuation and microbial contamination. It is recommended to aliquot the reconstituted solution into single-use portions immediately and store at -20°C. Any unused diluted solution should not be repeatedly frozen and thawed, as this may lead to peptide degradation and loss of biological activity. Operators should follow standard laboratory practices when weighing and handling the powder to prevent hydrolysis caused by ambient moisture.
