Protein Storage and Stabilization: Maintains near-neutral pH and isotonicity for preserving protein structure during short- and mid-term storage.

Size-Exclusion Chromatography (SEC): Used as an isocratic mobile phase to maintain protein integrity and reduce nonspecific interactions.

Affinity and Ion-Exchange Chromatography: Employed for column equilibration, sample loading, and washing to provide consistent ionic strength and pH.

Buffer Exchange and Dialysis: Serves as a target buffer to normalize samples prior to downstream biochemical analyses.

ELISA and Immunoassays: Used for sample dilution and reagent preparation to ensure reproducible binding conditions.

Western Blot Workflows: Applied for antibody dilution and membrane washing to minimize background while preserving antigen–antibody interactions.

Spectrophotometry and HPLC Sample Prep: Provides a defined ionic environment for reliable absorbance and chromatographic measurements.

Enzyme Assays: Offers a stable near-neutral pH and ionic strength for routine biochemical activity measurements.

Bacterial Cell Handling: Used for resuspension and washing of cells (e.g., Escherichia coli) under isotonic conditions.

Tissue and Cell Sample Processing: Utilized for gentle rinsing and dilution steps where physiological ionic strength is desired.
