Application


  • Partitioning recombinant chitinase from Nicotiana benthamiana by an aqueous two-phase system: Demonstrates the application of potassium phosphate monobasic in aqueous two-phase systems for efficient partitioning of enzymes, which is crucial for biotechnological and industrial applications (Tue et al., 2024).

  • Unlocking Nature′s Toolbox: This study showcases how potassium phosphate monobasic can be used to optimize conditions for the production of recombinant proteins, enhancing yields and streamlining production processes in biomanufacturing (Rajak et al., 2024).
