一般描述

MOPS (3-(N-吗啉基丙磺酸) 也称丙烷磺内酯缓冲液,是一种多功能 "Good′s缓冲液,广泛应用于生物学研究。它的结构类似于 MES(2-(N-吗啉基)乙磺酸),具有一个吗啉环。从生理学相关性(physiological relevance)来看, MOPS′的pKa 为7.2,与生理 pH接近, 这使其适用于需要近中性环境的研究。 与 MES(pKa 为6.1)相比,MOPS提供模拟生理环境的缓冲能力。

MOPS 在各种研究领域中发挥各种功能。 作为缓冲剂,它可用于稳定细胞培养基的 pH值,促进最优细胞生长和功能。此外,它可用于色谱法中的蛋白质纯化,稳定蛋白质溶液,并可用作各种电泳技术中的可靠缓冲液,实现生物分子的高效分离和分析。MOPS 也可以高效地溶解解细胞以便进行后续的蛋白质或核酸提取,并可以稳定溶液中的酶,确保研究用酶的活性。它是精细调节生长培养基pH 以实现最优生长的重要工具。

MOPS 具有额外的优点,例如与金属离子(特别是铜(Cu)、镍 (Ni)、锰 (Mn)、锌 (Zn)、钴(Co)离子)的相互作用极低,这一特性令其成为金属离子相关研究中的理想选择。它具有良好的水溶性,这一特性有助于其在各种缓冲液配方中的应用,也具有极低的脂溶性,这一点确保其不能透过膜并最大程度降低了对细胞过程的干扰。总而言之,MOPS 是一种广泛应用于各种生物学领域的可靠缓冲剂,其出众的特性包括多功能性、生理学相关性(physiological relevance)、最低的金属相互作用、易用性,可广泛应用于细胞生物学、蛋白质研究、电泳和生物化学研究。

应用

MOPS 已被用于:

  • 慢病毒颗粒生产中的细胞培养基添加剂成分
  • 作为微生物生长培养基的缓冲剂和细胞核提取缓冲液
  • 用于分离心脏线粒体的MMSE-A缓冲液的成分
  • 作为合成完全 (SC) 培养基的成分
  • 作为NADH荧光猝灭的缓冲液

特点和优势

  • 细胞生物学和生物化学研究的理想选择
  • 可用作电泳和蛋白质分离的缓冲液成分
  • 有效缓冲范围为pH 6.5-7.9 (25 °C),pKa为7.2 (25 °C)
  • 易溶于水
  • 最低的金属离子结合能力

包装

The DRYPOUR®packaging system for high-quality hygroscopic salts DRYPOUR®packaging:
  • The current DRYPOUR®packaging configuration is in a 50L nestable drum
  • 25KG-DP are the standard prepack offering
  • Smaller volumes can be put in the same drum for variable configurations
The benefits of DRYPOUR®:
  • Improves operational efficiency by reducing material preparation time and increasing operator safety
  • Minimizes caking of hygroscopic salts
  • Offers triple protection: against moisture inside and outside, and against contamination
How does the DRYPOUR®packaging system Improve your operational efficiency?
  • This state-of-the-art design packaging system minimizes caking, thus significantly reducing the time needed for material preparation
  • PE drum with our new tamper-evident seal, a polyethylene liner with integrated desiccant bags and a breathable interior Tyvek®liner
  • Desiccant bags are firmly integrated into the polyethylene liner
  • Triple protection delivers two invaluable results:
  1. Dramatically reduced caking
  2. No contamination risk from the desiccant
