General description
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 在 Mg 的体外实验中表现出了应用潜力。
Application
HEPES 已被用于:
- 在新型囊泡 - 芽殖方案中,作为储备溶液和缓冲溶液的一种组分
- 作为细胞内溶液的一种组分,用于制备脑片记录
- 作为亲和蛋白纯化过程中洗涤缓冲液、洗脱缓冲液和脱盐缓冲液的一种组分
- 在纯化蛋白质的热变性测定中,将 pH 维持在 7
- 使用凝胶过滤的蛋白质的等渗洗脱
- 与 NaCl 一起,用于 EPR(电子顺磁共振)光谱的样品制备
