The vial label identifies TB-500 as thymosin beta-4; this 43-residue peptide is presented for controlled cellular-signalling, peptide-characterisation and analytical research.
At 43 amino acids, TB-500 is among the larger peptides in the range, which calls for a correspondingly long RP-HPLC gradient and, in mass spectrometry, produces a multiply charged ion series requiring deconvolution to determine the mass. The formula contains exactly one sulfur atom (C212H350N56O78S), which belongs to the methionine residue near the N-terminus; its possible oxidation to the sulfoxide (+16 Da) is taken into account when MS identity data are interpreted.
Purity (≥99% by specification), CAS number 77591-33-4 and the molecular weight of 4963.5 g/mol complete the specification; the batch certificate of analysis is available for the product on request.
