TB-500 research material

“TB-500” is a commercial product name and is not, by itself, an unambiguous chemical identity. The active-lot specification and analytical report—not the product name—must control the sequence, molecular formula, molecular mass, formulation, measured content, purity, and reported tests for the material supplied.

Full-length thymosin beta-4 is a 43-residue peptide. The isolated LKKTETQ region is a distinct, shorter material. This listing does not describe the supplied material as full-length thymosin beta-4, its active region, Ac-LKKTETQ, or another fragment unless the active-lot documents establish that identity.

Documentation required before experimental use

  • Unambiguous sequence or molecular identity
  • Molecular mass or identity-test acceptance criterion
  • Nominal vial content and formulation matrix
  • Lot-specific identity, measured-content, and purity results
  • Test methods and lot number represented by each report

No actin-binding, angiogenic, regenerative, injury-recovery, or therapeutic effect is claimed for the material sold under this name.

Research-use boundary

For controlled laboratory research only. Not for administration to humans or animals, or for clinical, diagnostic, therapeutic, cosmetic, food, or veterinary use.
