TB-500 is a synthetic peptide corresponding to the biologically active region of Thymosin Beta-4 (Tβ4), a naturally occurring 43-amino-acid, actin-sequestering protein present in most mammalian cell types. Supplied as the acetate salt, TB-500 is used in laboratory settings as a reference form of the Tβ4 actin-binding motif, centered on the conserved LKKTETQ sequence. In the preclinical literature, Thymosin Beta-4 has been investigated for its role in actin regulation, cell migration, angiogenic signaling, and matrix and tissue remodeling across in vitro and animal model systems. Precision Research Peptides offers TB-500 (Thymosin Beta-4 Acetate) strictly as a research reference material for controlled experimentation.

TB-500 is the research designation for a synthetic form of Thymosin Beta-4 (Tβ4), an endogenous actin-sequestering peptide. Its most characterized biochemical property is the binding and sequestration of monomeric G-actin; reviews describe Tβ4 as the major actin-sequestering molecule in mammalian cells, a role that has been investigated in the context of cytoskeletal dynamics and cell motility.1 This actin-binding activity is not purely structural: research has localized an angiogenesis-associated site to the actin-binding region of the molecule, reporting that this domain is associated with vascular formation in experimental systems.2
In endothelial cell assays, Tβ4 has been examined for its role in directional cell migration, a process central to angiogenesis and matrix-remodeling research.3 Animal-model reviews have further catalogued Tβ4 investigation across dermal, corneal, and cardiac tissue-repair systems, framing it as a multifunctional regeneration-research peptide rather than a defined research reagent.4 Across this literature, Tβ4 shares actin-regulatory and pro-migratory pathways of interest with other cytoskeletal-active agents studied in tissue-remodeling research. Reported findings derive from in vitro and animal models and have not been established in humans.
