Product Description

TB-500 (also known as Thymosin Beta-4 fragment, Ac-LKKTETQ), a synthetic heptapeptide with strong tissue repair potential:

Basic Definition and Molecular Characteristics
TB-500 is the active core fragment of thymosin β4 (Tβ4, a natural 43-amino acid protein) (corresponding to amino acids 17-23, sequence Ac-Leu-Lys-Lys-Thr-Glu-Thr-Gln), with enhanced stability through N-terminal acetylation modification; CAS No. 885340-08-9, molecular weight 889.02 g/mol, appearing as a white lyophilized powder soluble in water/normal saline. It is not intact Tβ4, but retains the key functions of actin binding and cell migration regulation. Moreover, due to its small molecular weight, it exhibits excellent systemic distribution, distinguishing it from many repair peptides that only act locally.
