一般描述
HEPES 是一种通用两性离子缓冲液，不结合镁、钙、锰 (II) 或铜 (II) 离子。HEPES 已被Norman Good 博士和他的同事在 1966 年分类为 Good 缓冲液。在生物 pH 值为两性离子，在 pH 6.8～8.2 范围内最有效。
应用
HEPES 钠盐溶液适用于细胞培养研究。可用于制备 HEPES 缓冲液。可在透化成纤维细胞的磷酸化试验中用作缓冲液。可组成复合透析缓冲液，用于放射免疫法测定血清中游离甲状腺素。
其他说明
使用 HEPES 钠盐规格表可以非常方便地比较 HEPES 钠盐产品的规格。

When lysozyme is dissolved in a neutral HEPES buffer solution (pH = 7.4) with 0.001-0.050 M TCEP added, a fast phase transition process occurs and the resulting novel fiber-like hierarchical supramolecular assemblies made by primary spherical-particle aggregation can function as a "superglue"
