TB-500 (Thymosin Beta-4 Fragment) – 10mg

Overview of TB-500

TB-500 (Ac-LKKTETQ) is a synthetic heptapeptide corresponding to the N-acetylated active fragment of Thymosin Beta-4 (Tβ4), a highly conserved actin-sequestering protein found in almost all mammalian cells. In laboratory and in-vitro environments, the sequence has been studied extensively for its role in cellular dynamics, particularly its ability to bind to cellular actin.

By modulating actin polymerization, TB-500 is observed to facilitate rapid cell migration—a foundational process in cellular repair and regeneration models. Current research applications focus on its potential to influence angiogenesis (the formation of new blood vessels), mitigate inflammatory pathways, and support the accelerated regeneration of muscle, tendon, and endothelial tissues in isolated research models.

Research Applications:

• Actin Regulation: Investigating the modulation of actin polymerization and its direct effect on cellular mobility.

• Angiogenesis Models: Observing the promotion of new blood vessel formation in damaged or hypoxic tissue samples.

• Tissue Repair Studies: Analyzing cellular responses in muscle, ligament, and dermal repair assays.

• Inflammatory Pathway Modulation: Researching its cytoprotective properties and downregulation of inflammatory cytokines.
