Bachem – Your Partner for Bioactive Peptides

Thymosin β4 is a 43 amino acid peptide. It is the most abundant member of the β-thymosin family in mammalian tissue and is regarded as the main intracellular G-actin sequestering peptide. Thymosin β4 has multiple biological activities including prevention of apoptosis, reduction of inflammation, and promotion of angiogenesis and cell migration. Due to its role in protection and regeneration of injured or damaged tissue thymosin β4 has received considerable interest as a potential therapeutic agent. Most recently, Xiong et al. demonstrated that delayed administration of thymosin β4 significantly improved histological and functional outcomes in rats with traumatic brain injury.
