Thymosin Beta-4 Pro is the complete 43-amino-acid polypeptide form of Thymosin Beta-4 (Tβ4), one of the most abundant naturally occurring peptides in the human body. Unlike TB-500, which contains only the active binding domain, Thymosin Beta-4 Pro provides the full molecular sequence, enabling comprehensive research into all biological activities of the native protein. These include actin sequestration, cell migration promotion, angiogenesis stimulation, anti-inflammatory signaling, and stem cell activation. The full-length form is preferred for research requiring native protein behavior and for comparative studies against the truncated TB-500 fragment. Available in research-grade lyophilized form.
