Research summary
Most studies relate to full-length thymosin beta-4 rather than synthetic fragments, and are preclinical, with limited early clinical work in specific tissues. This summary describes what the literature has investigated. It is not a claim about the effects of our product, which is supplied for laboratory research only.
Mechanism of action
TB-500 is a synthetic peptide related to thymosin beta-4, a 43-amino-acid protein that binds monomeric actin. Published work on thymosin beta-4 has examined actin sequestration, cell migration, angiogenesis and tissue repair signalling in cell and animal models. Research-grade TB-500 is commonly described as based on the actin-binding region of the protein.
Chemical properties
Class: synthetic peptide related to thymosin beta-4. Form: lyophilised powder. Exact sequence, molecular weight, purity and identity: see the batch Certificate of Analysis (HPLC and mass spectrometry).
Storage and handling
Supplied as a lyophilised (freeze-dried) powder. Store sealed, cold, dry and protected from light, as stated on the Certificate of Analysis and product label. Allow the vial to reach room temperature before opening to limit condensation. Avoid repeated temperature cycling and humidity exposure. For laboratory research use only.
