Peptide Science research editorial team.

TB-500 10mg Extended Research Format

TB-500 10mg from Peptide Science is the 10 mg lyophilised vial of the full 43-amino-acid Thymosin Beta-4 protein, formatted for extended-duration cell-culture series or repeat-passage animal-model protocols where a larger working stock reduces vial-opening frequency. The complete native sequence is supplied as distinct from the 7-amino-acid active fragment listed elsewhere in this catalogue.

Beta-Thymosin Class Notes

Thymosin Beta-4 is the most abundant beta-thymosin protein in mammalian cytoplasm and is characterised in preclinical research for actin-sequestering activity via the KLKKTET motif at residues 17 to 23. The full-length 43-residue form has been studied for its effects on actin polymerisation, cell migration, vascular endothelial behaviour, and tissue regeneration.
