Buffer Stock Preparation: 500mM Sodium Phosphate stock used for rapid dilution to 10–100 mM working buffers at pH 7.0.

Protein Purification: Equilibration, wash, and elution buffer for ion-exchange and affinity chromatography at neutral pH.

Enzyme Assays: Maintains stable pH 7.0 for accurate enzymatic kinetics and activity measurements.

ELISA and Immunoassays: Wash and dilution buffer component; sterile and endotoxin tested for sensitive assays.

Cell Culture and Bioprocessing: pH-stable buffer component for media and supplements; suitable due to sterility and endotoxin control.

PBS Preparation: Used to prepare phosphate-buffered saline for washing, blocking, and sample handling.

Nucleic Acid Workflows: Compatible wash/dilution buffer in DNA/RNA purification and qPCR sample prep when phosphate is acceptable.

Dialysis and Desalting: Neutral pH buffer for protein buffer exchange and desalting to preserve structure and activity.

Microbial Culture: Maintains medium pH during cultivation of Escherichia coli, Staphylococcus aureus, and other bacteria.

Sample Storage: Neutral pH buffer for short-term stabilization of proteins and antibodies.
