一般描述
HEPES被描述为生物研究领域的最佳通用缓冲液之一。在生理pH条件下,该分子是两性离子,并且在pH 6.8至8.2(pKa 7.55)范围内是一种有效的缓冲剂。HEPES已被广泛用于各种应用,包括组织培养。它通常用于缓冲与空气接触的细胞培养基。HEPES可用于Mg的 体外 实验。它通常以5 mM至30 mM的浓度用于细胞培养。
应用
HEPES已可用于:
- 作为改良Eagle最小必需培养基的成分,用于 体外 培养生精细胞,并作为冷冻保护剂的成分,用于保存这些生殖细胞。
- 作为改良Ham's F-10的组分,用于孵育母鹿受精卵,以实现单倍体雄性半合子受体生产
- 制备90% Percoll溶液,用于Percoll梯度法以收集和制备精子
