Application
戊二醛固定动植物组织标本可引起脂质丢失，引起明显的形态学改变。当采用PIPES来缓冲戊二醛固定剂时，脂质的损失和伪影被最小化。，
当超细胞化学固定采用甲次砷酸盐-缓冲戊二醛时，碱性磷酸酶活性可选择性地从某些大鼠肝细胞细胞器丢失。当使用PIPES作为缓冲液时，活性的保留率要高于60%。
当在PIPE缓冲液采用戊二醛和甲醛配伍用作固定剂时，真菌孢子固片的荧光显微镜和电镜观察是最优的。

General description
PIPES是乙磺酸缓冲盐系列之一，由Good等人首先开发 以满足某些标准：中值pKa，最大水溶性和在所有其他溶剂中的最小溶解度，最小盐效应，pKa随温度的变化最小，化学和酶学稳定，在可见光或紫外光谱范围的最小吸收，易于合成。由于其在37℃的pKa接近生理pH，PIPES可应用于细胞培养工作。
Other Notes
Preparation Note
缓冲液制备可通过向PIPES游离酸中加入碱溶液，滴定到适当的pH值，或采用等摩尔的钠盐溶液和二钠盐溶液混合滴定到适当的pH值。
