Polymerase Chain Reaction (PCR): Used to prepare buffered solutions that maintain optimal pH for DNA polymerases during amplification.

Gel Electrophoresis: Used to make Tris-based running and gel buffers (e.g., TAE, TBE, Tris–glycine) that provide stable pH for nucleic acid and protein separation.

Protein Purification: Employed as the buffering component in ion exchange, affinity, and size-exclusion chromatography to stabilize protein structure and activity.

Enzyme Assays: Provides a consistent pH environment for kinetic measurements and activity assays of enzymes.

DNA/RNA Storage and Dilution: Used to prepare TE and related Tris-based buffers for nucleic acid stabilization and handling.

Restriction Digestion and Ligation: Serves as the buffering base for enzyme reaction mixtures to support endonucleases and ligases.

Western Blotting and Immunoassays: Used to prepare Tris-buffered saline (TBS) and transfer buffers for blotting, blocking, and washing steps.

Cell Lysis and Protein Extraction: Included in lysis buffers (e.g., Tris-based formulations) to maintain pH during protein solubilization.

Nucleic Acid Extraction and Plasmid Preparation: Used in buffers for plasmid isolation from Escherichia coli and other workflows.

Dialysis and Sample Desalting: Provides a stable pH reservoir for buffer exchange and desalting of proteins and nucleic acids.
