TB-500 is catalogued as a synthetic peptide corresponding to thymosin β4, a single chain of forty-three amino acid residues. The identifiers listed for it, CAS number 77591-33-4, the molecular formula C212H350N56O78S and a molecular weight of 4963.44 g/mol, are those of that full-length chain. No sequence is listed for this product.
A chain of this length is characterised in the same way as other long synthetic peptides: reversed-phase HPLC for the chromatographic profile, and electrospray mass spectrometry, in which the molecule appears as a series of multiply charged ions that are deconvoluted to a neutral mass for comparison with the expected value. That mass is the most direct check that a sample matches the full-length chain the identifiers describe. Each presentation is supplied as a lyophilised powder in a sealed vial.
TB-500 is a synthetic peptide corresponding to thymosin β4, a single chain of forty-three amino acid residues. Supplied as a lyophilised powder in a sealed vial for laboratory research. Available in a 10 mg presentation. Store the sealed vial at 2–8 °C for short-term storage, or at −20 °C and below for long term. Protect from light and avoid repeated freeze-thaw cycles.
