描述：

3-[N-Morpholino]propanesulfonic acid
Molecular Biology Reagent
Purity: 99+%
Free Acid
Useful buffer range: 6.5-7.9

Description: MOPS is a zwitterionic amino acid which acts as one of the "Good" buffers.¹ It is a structural analog to MES; however, MOPS is a more suitable biological buffer than MES because the pH range is closer to pH 7.4.

A buffer using MOPS free acid can be prepared by titrating the free acid with sodium hydroxide to the desired pH (pK_a ± 1), using about a half-equivalent of NaOH. A buffer using MOPS sodium salt can be made by mixing equimolar MOPS free acid and MOPS sodium salt solutions to attain a buffer of the desired pH. Titration of a solution of MOPS sodium salt with HCl results in a solution that will contain NaCl, so the ionic strength will be higher than appropriate for some applications.

Concentrations higher than 20 mM should not be used with mammalian cell cultures.

用途：生物缓冲液

适用于叶绿体薄层备样的电子传递和磷酸化研究；可以配制成多种琼脂培养基，在极限培养基中作为无毒缓冲液应用于棒状链霉菌（Streptomyces clavuligerus）的培养和头孢菌素（cephalosporin）的生产；可作为二维凝胶电泳中等电聚焦电泳（IEF）的电解质系统成分；还可应用于Northern杂交，作为RNA的分离和转膜时的缓冲液。

名称：3-(N-吗啡啉)丙磺酸 MOPS（有配好的缓冲液）

   英文：MOPS 3(N-MORPHOLINO)PROPANE-SULFONIC ACID

   CAS：1132-61-2

   介绍：MOPS是一种两性离子缓冲液，主要用用于配制作RNA 变性电泳缓冲液，缓冲范围是：6.5-7.9。在20mM的甲醛胶中作用尤为出色。多酚氧化酶（PPO）的活性测定会用到。

注意事项：

The pH of a 0.1 M solution of the sodium salt is approximately 10-12 and a 0.1 M solution of the free acid is approximately pH 2.5 to 4.0, depending on temperature. Solutions can be stored refrigerated for tup to approximately 6 months. Solutions should not be autoclaved¹; sterilization of solutions should be done by filter sterilization through a 0.2 um filter.
