使用TCEP (Tris(2-carboxyethyl)phosphine hydrochloride) is an alternative which is not pungent, more stable and works even at low pH. It is more selective, i.e. do not reduce metals and buried disulfides.

一般的な説明Tris (2-carboxyethyl) phosphine (TCEP) is very effective in cleaving disulfide bonds in aqueous solution. It dissolves in water and is odorless, unlike other trialkylphosphines (tributylphosphine). It is also less toxic than 2-mercaptoethanol. These advantages make it better than the other reducing agents.
