TB-500
5 mg

The complete thymosin β4 sequence, produced synthetically and supplied with an acetylated N-terminus. Thymosin β4 is a naturally occurring intracellular protein; its residues 17 to 23 form the LKKTETQ region that binds monomeric actin. This vial contains the whole protein, not that seven-residue region on its own.
