一般描述
HEPES 广泛应用于细胞培养，尽管细胞呼吸产生的二氧化碳浓度波动，但 HEPES 在维持生理 pH 值方面表现出色，这一特征在碳酸氢盐缓冲液中并不突出。它可以作为两性分离剂，在等电聚焦中产生 pH 梯度，与含有较少取代胺的缓冲液（如 Tris）相比，它对 DNA-限制性内切酶反应的干扰更小。除了这些应用之外，HEPES 还可以应用于各种生物和生化研究，包括免疫沉淀、细胞裂解和活细胞成像。通用性使其成为各种研究应用中不可或缺的工具。
应用
- 作为Danieau培养基中的一种成分，用于防止斑马鱼胚胎原肠胚形成后的黑色素形成
- 作为Hank溶液中的一个组分用于铁的降解检测
- 作为HEPES培养基中的一个组分用于细胞培养物的质粒转染
- 与RPMI-1640、L-谷氨酰胺、FBS、丙酮酸钠和β-巯基乙醇用于大鼠胰岛瘤细胞的培养
- 作为TCM199培养基中的一种补充剂用于核转移研究所需的新鲜卵母细胞洗涤
特点和优势
- 生化和生物学研究的高纯度产品
- 适用于细胞培养基
- 25°C 时，极易溶于水，pH 值范围为 6.8 - 8.2，pKa 为 7.5
