Bacteriophage Dilution and Storage: Maintains phage stability and infectivity during dilution series and short- to mid-term storage, commonly with Escherichia coli hosts.

Plaque Assays and Phage Adsorption: Supports efficient adsorption and plaque formation in soft agar overlays for coliphages on Escherichia coli.

Phage Lysate Preparation and Resuspension: Used to resuspend PEG/NaCl-precipitated phage pellets and clarify lysates while preserving particle integrity.

Elution of Phage from Samples: Facilitates recovery of phage from environmental or clinical matrices and membrane filters for downstream titering.

Host Cell Preparation for Infection: Serves as a wash or equilibration buffer for bacterial hosts (e.g., Escherichia coli) prior to phage infection.

Phage DNA Extraction Workflows: Provides a compatible ionic and pH environment for initial phage handling before nucleic acid purification.
