一般描述

HEPES被视为可用于生物研究的最佳通用缓冲液之一。在生理pH下,该分子是两性离子的,并在pH 6.8至8.2下可有效作为缓冲剂。HEPES已用于一系列应用,包括组织培养。它常用于在空气中对细胞培养基进行缓冲。HEPES可用于Mg的体外实验。

应用

HEPES已用于:
  • 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
