Electron Transport Studies
Satisfactory for studies involving electron transport and phosphorylation within chloroplast lamella preparations. This application leverages MOPS's buffering properties to maintain stable conditions for these sensitive biological processes.
Microbial Fermentation
Serves as a non-toxic buffering system for the extensive growth of microorganisms like *Streptomyces clavuligerus*. It is particularly useful in chemically defined media for cephalosporin production, ensuring optimal pH for cultivation and biosynthesis.
Electrophoresis Applications
Functions as a component of the electrolyte system in two-dimensional (2-D) gel electrophoresis. Its zwitterionic nature aids in the precise separation of proteins based on their charge and molecular weight.
