The complete 43-residue thymosin beta-4 — larger than, and not interchangeable with, the TB-500 fragment.
Presentation
Thymosin Beta-4 5 mg is supplied as a sealed vial of lyophilized material in USP Type I borosilicate glass, sealed under inert gas with an aluminium crimp. No diluent is included and nothing is pre-reconstituted, so concentration and aliquoting stay entirely in your laboratory's hands.
Quality release
- Chromatographic purity ≥ 98% by reverse-phase HPLC
- Identity confirmed by mass spectrometry against theoretical mass
- Lot code printed per fill and traceable to its certificate
- Visual inspection of the lyophilized cake before sealing
Laboratory handling
Add diluent slowly down the vial wall and swirl gently — do not shake or vortex. Work from net peptide content on the certificate when calculating molar concentration. Divide working solutions into single-use aliquots to avoid freeze–thaw loss.
Research use only. Not a drug, food, supplement or cosmetic. Not for human or veterinary use.
Current lot: PL26K1651. The certificate reports RP-HPLC purity, MS identity and net peptide content for this exact fill.
