TB-500 Research Compound (TB)

"Premium grade TB-500 validation."

TB-500 is a thymosin beta-4 peptide or its N-terminal actin-binding fragment carrying the LKKTETQ actin-binding motif, with full-length thymosin beta-4 (43 amino acids, ~4982 Da) documented as the major actin-sequestering molecule in eukaryotic cells. Thymosin beta-4 is studied in cell-migration and tissue-remodeling research for its reported effects on actin dynamics, dermal and corneal wound models, and angiogenesis (Goldstein et al., Trends Mol Med 2005, PMID 16099219; Low et al., Proc Natl Acad Sci USA 1981, PMID 6940133). TB-500 research peptide is supplied lyophilized at ≥99% purity verified by HPLC, with identity confirmed by mass spectrometry and a batch-specific Certificate of Analysis (COA) included. Store lyophilized powder at −20 °C, protected from light and moisture. For laboratory research use only — not for human or animal consumption.
