TB-500 is a synthetic version of the naturally occurring 43-amino acid peptide thymosin beta-4 (Tβ4). It is one of the most abundant intracellular proteins and plays a critical role in tissue protection, repair, and regeneration.
Store lyophilized TB-500 at -20°C for long-term storage. Once reconstituted, store at 2-8°C and use within 30 days. Avoid repeated freeze-thaw cycles.
Reconstitute with bacteriostatic water by gently injecting the solvent into the vial along the side wall. Allow the peptide to dissolve naturally without shaking or vortexing.
TB-500 is a synthetic analog of the active region of thymosin beta-4. While structurally similar, TB-500 is specifically designed for research applications with optimized stability and purity.
Every batch undergoes HPLC analysis for purity verification, mass spectrometry for identity confirmation, endotoxin testing (LAL), sterility testing, and amino acid analysis.
