Tris is extensively used in biochemistry and molecular biology.〔Gomori, G., (Preparation of Buffers for Use in Enzyme Studies ). Methods Enzymology., 1, 138-146 (1955).〕 In biochemistry, Tris is widely used as a component of buffer solutions, such as in TAE and TBE buffer, especially for solutions of nucleic acids. It contains a primary amine and thus undergoes the reactions associated with typical amines, e.g. condensations with aldehydes. ==Buffering features== Tris has a p''K''a of 8.07 at 25 °C, which implies that the buffer has an effective pH range between 7.5 and 9.0. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「tris」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
