Product Description

TB-500 Fragment 17-23 (Ac-GDKPDAE) is a shortened, N-terminally acetylated and C-terminally amidated synthetic derivative of the active core region (amino acids 17-23) of the naturally occurring thymosin beta-4 (TB-4) peptide.

This 7-amino-acid fragment contains the functional LKKTETQ-like motif believed to be primarily responsible for many of the actin-binding, cell-migration, and tissue-regenerative properties associated with full-length TB-500/TB-4 in preclinical research models.

Because of its dramatically reduced size compared to the 43-amino-acid parent molecule, the TB-500 Fragment 17-23 exhibits:

  • Improved stability against enzymatic degradation
  • Potentially enhanced tissue penetration
  • Greater resistance to rapid clearance
  • Simplified handling and reconstitution
  • Potentially offering superior bioavailability and a longer half-life

Common Research Applications

(For laboratory and in vitro research use only – not for human or veterinary therapeutic use)

  • Actin sequestration and cytoskeleton remodeling studies
  • Cell migration and wound-healing model research
  • Angiogenesis and neovascularization investigations
  • Anti-inflammatory pathway exploration
  • Fibrosis and tissue regeneration preclinical models
  • Dermatological and corneal injury research models
