TB-500
TB-500 is the synthetic form of the active actin-binding region of thymosin beta-4, a naturally occurring 43-amino-acid protein.
Research applications centre on cell migration, actin sequestration and angiogenesis assays in regeneration models.
This listing is the 5mg presentation of TB-500. Each lot is assayed by reverse-phase HPLC to ≥99% and confirmed by LC-MS against the expected mass. Vials ship sealed and desiccated, are stable at ambient temperature in transit, and should be stored at −20 °C on arrival. Reconstituted material is kept refrigerated and used within the window defined by your own protocol. Orders placed before the daily cut-off are typically dispatched within 24 hours from the UK, with tracked delivery across the UK and the European Economic Area.
- What purity is TB-500 tested to?
- Every lot of TB-500 is assayed by reverse-phase HPLC to ≥99% and identity-confirmed by LC-MS. The result printed on your certificate is the result for the lot number on your vial, never a generic or representative figure.
- Does TB-500 come with a certificate of analysis?
- Yes. A lot-specific certificate of analysis is issued with every vial, showing the HPLC purity trace, mass-spectrometry identity confirmation and the lot number. Analysis is carried out by an independent partner laboratory.
- How should TB-500 be stored?
- Store the sealed, lyophilised vial at −20 °C and keep it desiccated. The powder is stable at ambient temperature during transit. Once reconstituted, material is refrigerated and used within the timeframe your protocol specifies.
- Do you ship TB-500 to the UK and Europe?
- Yes. Orders are dispatched from the UK, typically within 24 hours of payment clearing, with tracked delivery to the United Kingdom and to the European Economic Area countries we currently serve. UK pricing is in pounds sterling and EU pricing is in euros.
- Is TB-500 suitable for human or veterinary use?
- No. TB-500 is an unlicensed reference standard supplied strictly for in-vitro laboratory research by qualified professionals. It is not a medicine, dietary supplement or cosmetic, and must not be administered to humans or animals.
