Polymerase Chain Reaction (PCR): Used in PCR master mixes and dilutions to maintain an optimal pH (~8.2) for polymerase activity.

Gel Electrophoresis (DNA/RNA): Component for preparing Tris-based buffers (e.g., TAE/TBE) that provide stable pH during nucleic acid separations.

Protein Electrophoresis (SDS-PAGE/native PAGE): Used in Tris-glycine buffers and gel solutions to ensure consistent pH during protein separation.

Western Blotting: Included in Tris-glycine transfer buffers to facilitate efficient protein transfer to membranes.

Protein Purification/Chromatography: Provides pH control in wash and elution buffers for ion exchange and affinity workflows.

Enzyme Assays: Serves as a stable buffering system at pH 8.2 for reliable kinetic and activity measurements.

Nucleic Acid Storage and Dilution (TE buffer): Used to prepare Tris-based buffers for stable DNA/RNA storage and handling.

Plasmid Preparation: Used in resuspension and buffer systems for isolating plasmid DNA from Escherichia coli cultures.

Cell Lysis and Protein Extraction: Included in lysis and extraction buffers to stabilize proteins from mammalian cells and Escherichia coli.
