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。由于它在37 °C的pKa接近生理pH，PIPES还可用于细胞培养工作。

Application

使用PIPES用于分离琼脂糖凝胶中的乙醛酸化RNA、核酸酶S1的RNA作图以及核糖核酸酶保护检测的实验方法已被报道。PIPES已被用作戊二醛固定组织样品的缓冲液。,
PIPES已被用于蛋白结晶。， PIPES在tubulin
α和β亚基在免疫吸附凝胶上解析后进行重构的应用已被描述。PIPES已被推荐用于半胱天冬酶3、6、7和8体外研究的缓冲液中。
一项已发表的研究表明了PIPES在蛋白质分析等应用中可作为非金属离子络合缓冲液。PIPES在细胞培养中已被用于如在大肠杆菌中对热稳定突变膜蛋白进行工程化改造等应用。

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。

Analysis Note

BioXtra PIPES已经过痕量元素分析。特定批次的结果见分析证书(CoA)。 BioXtra PIPES适用于需要严格控制元素含量的应用。

Other Notes

Sigma-Aldrich公司提供生物性能认证的细胞培养用PIPES(产品编号 P1851) 以及其他几种不同的盐类，以为缓冲液制备提供便利。

The poor stability of membrane proteins in detergent solution is one of the main technical barriers to their structural and functional characterization. Here we describe a solution to this problem for diacylglycerol kinase (DGK), an integral membrane protein from Escherichia

Of the 20 well-known buffers proposed by Good, all but 3 form metal ion complexes which can result in serious interferences, particularly in protein analyses. The structural features responsible for such complex formation have been identified. Based on a mechanistic

The dissociation and separation of the tubulin alpha- and beta-subunits have been achieved by binding alpha-subunits to an immunoadsorbent gel and selectively inducing release of free beta-subunits. The immunoadsorbent gel was prepared by coupling the monoclonal antibody YL1/2 to Sepharose
