Ask AssistantThymosin-Beta-4-Fragment (1-4) (Ac-SDKP) is a synthetic research peptide that corresponds to a segment of Thymosin-Beta-4, a 43-amino-acid-long actin-binding protein involved in the organization of the cytoskeleton. Preclinical studies show that TB-500 modulates actin polymerization, cell migration, and angiogenic signals, primarily via the β-actin/G-actin regulatory cycle. It is widely studied due to its role in tissue remodeling, cellular motility, and regenerative mechanisms in controlled laboratory environments.
