• Description

  Research-grade TB-500 — 10mg lyophilized peptide supplied with a separate vial of sterile diluent (0.3% potassium sorbate). TB-500 is full-length Thymosin Beta-4, a 43-amino-acid peptide studied for its role in actin polymerisation and cellular migration. 99%+ purity verified by an independent third-party lab via HPLC and mass spectrometry.

  TB-500 is full-length Thymosin Beta-4, a 43-amino-acid peptide studied for its role in actin polymerisation and cellular migration. The same compound is also stocked in vial form.

  Supplied with sterile water preserved with 0.3% potassium sorbate; no separate bacteriostatic water is needed.

  WHAT RESEARCHERS LOOK AT

• Frequently Asked Questions

  DO I NEED TO BUY BACTERIOSTATIC WATER SEPARATELY?

  No. Every nasal spray ships with its own diluent — sterile water preserved with 0.3% potassium sorbate, supplied with every spray. This differs from the lyophilized vials in our catalogue, which are reconstituted with bacteriostatic water sold separately.

  WHAT IS TB-500?

  TB-500 is full-length Thymosin Beta-4, a 43-amino-acid peptide studied for its role in actin polymerisation and cellular migration.

  IS THIS THE FULL-LENGTH PEPTIDE OR THE 17-23 FRAGMENT?

  This is the full-length peptide — all 43 amino acids of Thymosin Beta-4. Durham Peptides lists TB-500 Frag 17-23 as a separate product, and that one contains only the seven-residue Ac-LKKTETQ actin-binding fragment. They are different materials and are not interchangeable. If the protocol calls for the short fragment, order the TB-500 Frag 17-23 listing instead.

  HOW SHOULD IT BE STORED AFTER RECONSTITUTION?

  Keep the bottle refrigerated at 2–8°C and protected from light both before and after reconstitution. Once reconstituted, use within an appropriate research timeframe — a peptide in solution has a materially shorter usable life than the sealed lyophilized material.

  HOW IS IT SHIPPED IN CANADA?

  Orders placed and paid before 3:00 PM ET ship the same business day via Canada Post Xpresspost with full tracking. Shipping is domestic from within Canada, so there are no customs delays or border holds.

  IS THE COA VERIFIABLE?

  Yes. Every batch is independently lab-tested with a unique report key you can confirm independently — see our guide on how to verify a lab report key.
