We offer peptides for sale as Thymosin Beta (TB4) Tb-500 2 mg. This Polypeptide listing supplies Thymosin Beta, also written TB4 or TB-500, at 2 mg. Thymosin beta-4 is a 43-amino-acid actin-binding protein present in nearly all cells, and the several names on the label reflect how the same material is described in different markets rather than different substances.
Its function is cytoskeletal. Actin monomers are held by the peptide and released as filaments are built, which influences cell shape, movement and the reorganisation that happens during repair. Research on thymosin beta-4 follows that into migration studies, vascular responses and muscle tissue, and animal work has looked at cardiac repair after injury. Those are model systems, and their findings describe the peptide under those conditions.
Why the brand matters for this one
TB-500 is a label rather than a sequence specification, so two products with the same name can differ in what they contain. This is the Polypeptide item at 2 mg, and the brand and amount together identify it against the Peptide Sciences TB-500 entries at 2, 5 and 10 mg. Matching brand and milligram figure is the reliable way to compare.
A protein of this size is not a growth hormone secretagogue, and its actin-binding mechanism has nothing in common with GHRH or ghrelin receptor signalling. The 2 mg quantity is the labelled amount.
The protein was first isolated from the thymus in the early 1980s, and its name reflects that origin rather than an immune function; the actin-binding role came later. It is abundant in platelets and in neural tissue, and its 43-residue chain has no disulfide bonds, which is part of why it behaves as a flexible protein in solution. That flexibility is relevant to how it binds actin, and it is why the protein is usually described by length rather than by a rigid structure.
