TB-500

Thymosin Beta-4 Fragment for Research

$59.99

Overview

TB-500 is a synthetic, N-terminally acetylated seven-amino-acid peptide that matches residues 17-23 of human thymosin beta-4. Its sequence is Ac-LKKTETQ.

TB-500 is an investigational research material and is not an FDA-approved drug. For laboratory research use only. Not for human or veterinary consumption. Not intended to diagnose, treat, cure, or prevent any disease. TB-500 is also prohibited in competitive sport under the 2026 World Anti-Doping Agency Prohibited List.

Research Details

TB-500 is different from full-length thymosin beta-4, which has 43 amino acids. Laboratory studies of TB-500 have focused mainly on identification, peptide stability, metabolic cleavage, and its metabolites. Direct evidence for TB-500 is limited, and findings from full-length thymosin beta-4 cannot be assigned to this shorter fragment.

Research has identified TB-500 as N-acetylated Ac-LKKTETQ and examined its metabolism and detection with mass spectrometry.

Research areas include:

  • Peptide identification by LC-MS/MS
  • In vitro stability and degradation studies
  • Peptide-metabolite profiling
  • Comparative thymosin beta-4 fragment analysis
  • Structure-activity relationship research
  • Fibroblast migration assay development
  • Analytical-method validation
