Usage

Uses

Used in Biochemistry and Molecular Biology:
MOPS sodium salt is used as a buffering agent for maintaining a stable pH environment in cell culture media, electrophoresis running buffers, and protein purification chromatography processes. Its zwitterionic nature and lack of metal ion complexation make it an ideal choice for these applications.
Used in Cell Culture Media:
MOPS sodium salt is used as a buffering agent in buffered culture media for various cell types, including bacteria, yeast, and mammalian cells. It helps maintain a consistent pH, which is crucial for optimal cell growth and function.
Used in Electrophoresis:
MOPS sodium salt is utilized as a running buffer in electrophoresis techniques, such as agarose gel electrophoresis, to separate RNA and other biomolecules based on their size and charge. Its buffering capacity ensures a stable pH throughout the process.
Used in Protein Purification:
In chromatography, MOPS sodium salt serves as a buffering agent during protein purification. Its non-coordinating properties with metal ions help prevent unwanted interactions and maintain protein integrity.
Used in Bicinchoninic Acid (BCA) Assay:
MOPS sodium salt is suitable for use in the BCA assay, a colorimetric method for determining protein concentration. Its buffering capacity helps maintain a stable pH environment, ensuring accurate and reliable results.
Used in pH Adjustment:
MOPS sodium salt can be mixed with MOPS free acid to achieve the desired pH in various solutions. Alternatively, MOPS free acid can be titrated with sodium hydroxide to attain the required pH level.
Sterilization:
It is recommended to sterilize MOPS buffers by filtration rather than autoclaving due to the formation of unknown yellow degradation products that may occur after autoclaving.
