Identity and class
Synthetic peptide fragment of Thymosin β4
A synthetic sequence corresponding to the actin-binding region of naturally occurring Thymosin β4, a 43-amino-acid protein.
The commonly supplied research fragment has a molecular weight in the range of approximately 4963 Da for the full Thymosin β4 protein; TB-500 refers to the synthetic analog/fragment used in laboratory research.
