Synthetic thymosin β4 fragment
TB-500 is a synthetic fragment of thymosin β4, a naturally occurring peptide involved in cell migration and actin regulation. It is widely used as a research tool in recovery and tissue-repair studies.
Each kit is 10 identical vials. Minimum 1 kit (10 vials) to the EU · 3 kits (30 vials) to the US. Free EU shipping.
Plain, unbranded packaging. No product names, no logos — nothing on the outside indicating what is inside. Tracked to a DPD Locker or your address.
For laboratory and in vitro research use only. Not for human or veterinary use, and not for use in diagnostic procedures.
TB-500 is a synthetic version of the active region of thymosin β4, a naturally occurring peptide that plays a role in actin regulation and cell migration. It is commonly paired with BPC-157 in tissue-repair research and is supplied as a lyophilized 10-vial kit.
RetaNord supplies TB-500 as a fixed kit of 10 lyophilized vials, each verified at 99%+ identity purity by HPLC with identity confirmed by mass spectrometry. Supplied for laboratory and in vitro research use only.
