Frequently asked questions

Research use only. Not for human or veterinary use.

What is TB-500?

TB-500 is a synthetic peptide corresponding to the active region of thymosin beta-4. As supplied under CAS number 885340-08-9 (PubChem CID 62707662), it has the molecular formula C38H68N10O14 and a molecular weight of 889.0 g/mol, with the sequence Ac-Leu-Lys-Lys-Thr-Glu-Thr-Gln-OH. Oasis Labs supplies it as a lyophilized powder at 99%+ documented purity for laboratory research use only.

What is the difference between TB-500 and thymosin beta-4?

They are related but distinct. Thymosin beta-4 is the full 43-residue protein, CAS 77591-33-4, molecular formula C212H350N56O78S, molecular weight 4963 g/mol. TB-500 as catalogued under CAS 885340-08-9 is the short active fragment, C38H68N10O14 at 889.0 g/mol. The two are frequently conflated in the vendor market, which is exactly why the lot-specific Certificate of Analysis is the definitive statement of what a given vial contains.

What has TB-500 been studied for in research settings?

Published preclinical literature has investigated the thymosin beta-4 active region in in vitro and animal models, with reported work centring on actin binding and cell migration pathways in those experimental systems. Oasis Labs supplies this material strictly as a research reagent. No human or veterinary use is described, supported or intended.

What are the specifications for Oasis Labs TB-500 10mg?

SKU TB500-10MG. Supplied as a 10mg vial of white to off-white lyophilized powder at 99%+ documented purity by HPLC. Molecular formula C38H68N10O14, molecular weight 889.0 g/mol, CAS 885340-08-9. Solubility and physicochemical data are given on the lot-specific Certificate of Analysis, which is the definitive statement of the identity of the supplied material.

Where can researchers buy TB-500 with third-party testing?

Oasis Labs supplies TB-500 10mg direct to researchers from the USA at $57.00 per vial. Every lot is third-party tested and the Certificate of Analysis is published openly rather than supplied only on request. The TB-500 COA is available at myoasislabs.com/coa/tb-500-10mg/ and the full testing methodology is documented at myoasislabs.com/coa-process/.

Is Oasis Labs TB-500 intended for human use?

No. This product is sold FOR RESEARCH USE ONLY and is not for human or veterinary use. It is intended exclusively for in vitro laboratory research conducted by qualified professionals. It is not a drug, food, cosmetic or medical device, and nothing on this page describes or recommends administration to humans or animals.
