About TB-500

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.

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.

Questions about TB-500

TB-500 is a synthetic peptide corresponding to thymosin β4, a single chain of forty-three amino acid residues. It is supplied in a sealed vial as a white to off-white lyophilised powder, in a 10 mg presentation.

Yes. TB500 and TB 500 are other spellings of TB-500, catalogued under CAS number 77591-33-4 with the molecular formula C212H350N56O78S.

TB-500 is catalogued as a synthetic peptide corresponding to thymosin β4, a single chain of forty-three amino acid residues. Its CAS number, formula and molecular weight are those of that full-length chain.

4963.44 g/mol, for the molecular formula C212H350N56O78S. At this mass electrospray LC-MS shows a series of multiply charged ions, which are deconvoluted to one neutral mass for comparison with the expected value.

77591-33-4. The same identifiers give the molecular formula C212H350N56O78S and a molecular weight of 4963.44 g/mol, and they appear in the specifications on this page.

Forty-three, in a single linear chain. That length puts TB-500 among the longer synthetic peptides in the catalogue, at close to 5 kDa.

By electrospray mass spectrometry, deconvoluting the multiply charged ions to a neutral mass and matching it to the full-length chain, while reversed-phase HPLC gives the purity as the main peak's share of total peak area.

Order TB-500 directly from British Peptide Labs, a UK-registered company. It is supplied in a sealed 10 mg vial at £75.00 (£7.50 per mg). Every vial is ≥99% purity (HPLC), with independent third-party testing by PeptideVerify. Orders placed before 3pm Mon–Sat leave the same day by Royal Mail Tracked 24 for next-day tracked delivery.

TB-500 comes in one sealed vial: 10 mg at £75.00 (£7.50 per mg). Delivery is free on every order.

TB-500 is catalogued in the Peptide Fragments research area, where compounds are grouped by molecular class. The research area page lists each of them with its identifiers.
