Dragon Pharma TB-500 (Thymosin Beta-4)

Dragon Pharma TB-500 is a premium-quality synthetic peptide manufactured to rigorous laboratory standards for scientific and research applications. TB-500 is a synthetic analogue of Thymosin Beta-4 (Tβ4), a naturally occurring 43-amino-acid peptide that is widely distributed throughout mammalian tissues and recognized for its involvement in cellular migration, tissue remodeling, angiogenesis, and regenerative biology.

Thymosin Beta-4 functions as a multifunctional regulatory peptide with several biologically active regions responsible for distinct physiological processes. The N-terminal region has been investigated for anti-inflammatory and antifibrotic activity, while the central actin-binding domain containing the LKKTET motif plays an important role in cytoskeletal organization, endothelial cell migration, angiogenesis, and wound repair. TB-500 represents the biologically active region of this peptide and has become one of the most extensively studied compounds in regenerative medicine and tissue engineering.

Researchers continue investigating TB-500 in laboratory models involving connective tissue repair, cardiovascular biology, skeletal muscle regeneration, liver physiology, ocular healing, neurological research, stem cell biology, and extracellular matrix remodeling.

Every batch of Dragon Pharma TB-500 is manufactured under strict quality control procedures to ensure exceptional purity, consistency, and molecular integrity. The peptide is supplied as a lyophilized (freeze-dried) powder without unnecessary fillers, preserving stability during storage while providing dependable performance for laboratory research.

Peptide Specifications

Molecular Structure and Biological Activity

Thymosin Beta-4 is an endogenous actin-binding peptide naturally expressed throughout numerous tissues where it participates in cellular organization, migration, differentiation, and tissue maintenance. The peptide regulates G-actin sequestration, allowing precise control of cytoskeletal remodeling that is essential for cell movement, wound repair, angiogenesis, and tissue regeneration.

TB-500 has been extensively investigated because it reproduces many of the biological activities associated with Thymosin Beta-4 while providing researchers with a stable synthetic peptide for laboratory investigation.

Experimental studies continue to examine its influence on endothelial cells, fibroblasts, keratinocytes, stem cells, cardiomyocytes, neuronal tissues, and connective tissue remodeling.
