Product description
Published context, clearly separated from lot claims.
A technical catalog should make the chemical record, relevant experimental literature and product-specific documentation independently reviewable.
TB-500 is an acetylated heptapeptide corresponding to amino-acid residues 17–23 of thymosin β4, an actin-sequestering peptide. Distinguishing this fragment from full-length thymosin β4 is essential for identity, formula, mass and literature interpretation.
Published research reported inhibition of PDGF-BB-stimulated hepatic stellate-cell proliferation and migration at 10 ng/mL. A separate mouse study evaluated topical TB-500 in a skin-wound model. These are experimental observations and are not administration guidance.
Selected published findings
- Corresponds to the actin-binding-domain region of thymosin β4.
- Inhibited PDGF-BB-stimulated hepatic stellate-cell proliferation and migration in a published cellular study.
- Was evaluated in a non-clinical mouse skin-wound model.
