Research question

What is TB-500, and how does it relate to thymosin beta-4?

The short answer

Answered from published research literature only. It describes what that literature examines; it is not a statement about use in people. TB-500 is investigational research material and is not an approved product.

TB-500 is a synthetic, N-acetylated seven–amino-acid fragment. The same commercial name is also used for full-length thymosin beta-4, a 43-residue protein, so the name alone does not determine which molecule is in a given vial.1285225817468232

The published literature under the beta-thymosin heading concerns actin binding and the structural biology of the family. The seven-residue fragment and the full-length protein are different molecules within it.1749524812852258
