Tb-500 mechanism of action?

In the research literature, TB-500 is described as a synthetic acetylated fragment corresponding to the actin-binding region (residues 17-23) of thymosin beta-4, studied in cell-migration and actin research. It is classed as a peptide. This describes its use as a laboratory research tool only, not any effect in people. Sable Peptides supplies it for laboratory research use only; it is not for human consumption.
