DTBA(Protein Modifier) M120 Dithiobutylamine, 99+%f.w.: 137.23 daltons |
Dithiobutylamine (DTBA) is simply the best reducing agent for reducing disulfide bonds. Approximately 20% of human proteins are predicted to contain disulfide bonds between cysteine residues. DTBA has thiol pKa values that are approximately 1 unit lower than DTT and forms a disulfide with a similar E value. Dithiobutylamine reduces disulfide bonds faster than DTT, especially in neutral aqueous systems. The amino group of DTBA enables its isolation by cation exchange and facilitates its conjucation. DTBA is simply the best reagent for reducing disulfide bonds in aqueous solutions. Dithiobutylamine has very desirable physicochemical attributes. The HCl salt of DTBA is nearly odorless with a high solubility in water.
