Overview
TB-500 research material, available in 5 mg, 10 mg vials. For in-vitro research only.
Store the sealed vial at −20 °C, protected from light and moisture. Once reconstituted, store at 2–8 °C and avoid freeze–thaw cycles.
Bacteriostatic water is added slowly down the inside wall of the vial, then swirled until the cake dissolves. Concentration follows from the diluent volume.
Research summary
- High resolution mass spectrometry of the TB-500 formulation identified the N-terminally acetylated 17 to 23 fragment of human thymosin beta-4, and the same fragment was then made by solid phase synthesis to confirm the assignment. [1] [2]
- An examination of products sold online as TB500 and TB1000 found their contents were not systematically consistent with the descriptions attached to those names. [3]
- In work on the full-length protein, a thymosin beta-4 variant missing residues 17 to 23 showed no interaction with G-actin at all, which places the actin binding motif inside exactly the stretch the product name refers to. [4]
- In two separate assays the parent acetylated fragment was not the active species: human hepatic stellate cell effects tracked the unacetylated 17 to 23 peptide, and scratch closure in fibroblasts tracked the metabolite Ac-LKKTE rather than the parent. [5] [6]
