PBS Preparation: Stock component to prepare phosphate-buffered saline (PBS) from 0.5M Sodium Phosphate Dibasic for cell culture, washing, and storage.

Cell Culture and Microbiology: Buffers media and wash solutions to maintain physiological pH during growth of Escherichia coli and other bacteria.

Protein Purification: Common buffer for ion-exchange and IMAC workflows, providing stable pH during binding, wash, and elution steps.

Enzyme Assays: Maintains consistent pH for enzymatic reactions where phosphate buffer is compatible with enzyme activity.

Immunoassays (ELISA/Western Blot): Used in PBS-based wash and dilution buffers to stabilize proteins and antibodies.

Chromatography Mobile Phase: Serves as a phosphate buffer component for HPLC and FPLC methods requiring precise pH control.

Histology and Fixation: Used to prepare phosphate-buffered formalin for tissue fixation and immunohistochemistry workflows.

Dialysis and Buffer Exchange: Provides a stable buffering environment for desalting and sample conditioning.

Sample Storage and Stabilization: Helps maintain pH for protein and antibody storage solutions.

pH Adjustment and Titration: Employed as a standardized 0.5M Sodium Phosphate Dibasic stock to set and maintain target pH in biochemical buffers.
