一般說明
1, 4-哌嗪二乙磺酸（PIPES）是一种两性离子缓冲液，属于乙磺酸缓冲液系列，由Good等人率先推出，是一种用于细胞培养、电子显微镜组和其他生物学应用织固定的无毒缓冲液。PIPES 不与金属离子相互作用。由于其在37°C时的pKa接近生理pH，因此在生物、生化和环境研究中被用作缓冲物质。PIPES满足特定的标准：中值pKa，最大水溶性且在所有其他溶剂中的溶解度极小，盐效应极低，pKa随温度变化极小，化学和酶学稳定，在可见光或紫外光谱范围吸光度极小，易于合成。可将碱溶液添加到不含 PIPES 的酸中并滴定至适当的 pH 值，或通过混合单钠盐和二钠盐的等摩尔溶液并滴定至适当的 pH 值，制备缓冲液。
應用
PIPES 钠盐缓冲液可用于：
- 配制 BRB80 缓冲液，以通过荧光显微镜对动态微管和单个驱动蛋白分子成像
- 作为 PEM 固定液成分
- 复溶红细胞 (RBC)，以研究 pH 对 5 配位α-亚硝酰血红蛋白 (HbNO) 稳定性的影响
特點和優勢
- 无毒
- 易用
- 热稳定
- 易于处理和储存
儲存類別代碼

Increased osmotic pressure has been reported to cause non-cytotoxic histamine release (HR) from human basophils, as well as a potentiation of HR induced by anti-IgE. In this study, the effects of hyperosmolar Na-K-acetate (300-600 mOsm/kg H2O) on HR was studied

Maximal rates of renal hydrogen ion secretion and bicarbonate reabsorption in the dogfish were stimulated by intravascular infusion of acidic and basic buffers: bicarbonate, phosphate, phenol red, dimethadione (DMO), imidazole, and piperazine-N,N'-bis(2 ethanesulfonic acid) (PIPES). There was no difference in
