TB-500
Ac-LKKTETQ / Thymosin beta-4 fragment
- Peptide length
- 7 amino acids
N-acetylated heptapeptide in the cited study
Research contextPredominantly preclinical
Read the linked studies for their methods and limitations.
An analytical study identified TB-500 as N-acetylated LKKTETQ, a short region of thymosin beta-4. The market name is also used inconsistently.

Read the evidence
Evidence for full-length thymosin beta-4, including ophthalmic trials, does not automatically apply to this fragment.
Resolve the identity
The product name alone cannot distinguish a seven-residue fragment from the 43-residue parent. Require intact mass and sequence.
