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: pre-filled pen. Exact sequence, molecular weight, purity, identity and content: see the batch Certificate of Analysis.
Storage and handling
Supplied as a pre-filled pen. Store as stated on the product label and Certificate of Analysis, typically cold and protected from light. Avoid freezing and repeated temperature cycling unless the label states otherwise. For laboratory research use only.
