描述

Citrate BIS-TRIS propane (CBTP) is a buffer system useful across pH 2.5 to 9.5.

Using CBTP one can use a single buffer system to screen pH 2.5 to 9.5 by varying the ratio of Citric acid to BIS-TRIS propane. Although the two buffer reagents are made available separately for convenient, individual replacement, they are designed to be used together, with the supplied CBTP buffer titration table to create a crystallization buffer system covering pH 2.5 to 9.5.

柠檬酸盐 BIS-TRIS 丙烷 (CBTP) 是一种适用于 pH 2.5 至 9.5 的缓冲系统。

使用 CBTP，可以使用单一缓冲系统通过改变柠檬酸与 BIS-TRIS 丙烷的比例来筛选 pH 2.5 至 9.5。虽然这两种缓冲试剂是分开提供的，以便于单独更换，但它们被设计为一起使用，与提供的 CBTP 缓冲液滴定表一起创建一个涵盖 pH 2.5 至 9.5 的结晶缓冲系统。

Solutions are stable at 2-8°C for months. Autoclaving is not recommended for any sulfonic acid buffer. When MES solutions are autoclaved, they turn yellow (although pH does not change measurably). The identity of the yellow breakdown product is unknown. When MES solutions are stored at room temperature, they can turn yellow within six months.
