About TB-500
TB-500 is a synthetic version of Thymosin Beta-4 (Tβ4), a naturally occurring 43-amino-acid peptide found across a wide range of mammalian tissues and cell types. It is one of the principal actin-sequestering molecules in the body, binding monomeric G-actin and participating in the regulation of the cellular cytoskeleton.
Because of this role, TB-500 is widely used in laboratory research examining actin dynamics, cell migration, and tissue-remodeling models. Every batch we supply is sourced from vetted manufacturing partners and independently verified in the U.S. for identity and purity before it reaches your bench.
