TB-500 is a synthetic version of the active fragment of thymosin beta-4, studied in preclinical models of cell migration, actin regulation, and tissue repair processes.
TB-500 is a research peptide reproducing the active region of thymosin beta-4, a naturally occurring actin-binding protein present in nearly all cell types. By sequestering actin monomers it influences cell migration and cytoskeletal dynamics, and it appears widely in preclinical studies of wound repair, cardiac tissue models, and inflammation resolution.
Research Applications
Handling & Storage
Supplied as a lyophilized powder. Store sealed vials in a cool, dry place away from light; refrigerate after reconstitution with bacteriostatic water and avoid repeated freeze-thaw cycles.
This compound is intended for in-vitro research and laboratory use only. Not for human consumption.
