Because of the amido and carboxyl, amino acid is ampholyte so that it exists as a sort of zwitterions or dipole ionic when it dissolves in the water or in crystal.

氨基酸同時含有氨基和羧基，是兩性電解質，在水溶液或結晶內基本上均以兩性離子或偶極離子的形式存在。

This technology can form smooth pH gradient by adding ampholyte and make protein stop electrophoresis at the isoelectric points.

該技術是通過加入兩性電解質，形成較平滑pH梯度，使樣品在等電點處停止電泳。

The new equipment can be applied to separate inorganic ions and some improvements for equipment and further research on conditions of electrophoresis should be undertaken to separate ampholyte amino acid.

新設計的垂直電泳裝置適合用于無機離子的分離，如用于分離兩性電解質氨基酸還需進一步研究電泳條件或改進裝置。

Analysis of band type of animal HB by IEF technique with domestic ampholyte

應用國產兩性電解質對動物血紅蛋白譜型的分析

It can also be applied to determine ampholyte such as protein and amino acid.

該計算公式也可應用到蛋白質、氨基酸等兩性電解質的線性滴定分析上。
