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。
