About this compound
The Ac-SDKP tetrapeptide is the biologically active C-terminal fragment of Thymosin Beta-4. It binds G-actin and regulates actin polymerization dynamics. In cell culture, it promotes endothelial cell migration and tubulogenesis through α4β1 integrin interactions. Cytoskeletal dynamics studies, endothelial migration assays, cardiac fibrosis research models, and angiogenesis experiments.
