DNA/RNA Elution and Resuspension: Commonly used as a low-salt buffer (10 mM Tris-HCl, pH 8.5) to elute and resuspend nucleic acids from spin columns or pellets while preserving integrity.

Nucleic Acid Dilution: Provides stable pH for diluting DNA, RNA, and oligonucleotides for cloning, sequencing, and library prep.

PCR/qPCR and RT Reactions: Serves as a buffering component to maintain optimal pH for polymerases and reverse transcriptases during amplification workflows.

Enzyme Assays and Dilutions: Used as a base buffer for preparing and diluting enzymes (e.g., polymerases, nucleases) to ensure consistent activity and stability.

Cloning and Plasmid Workflows: Maintains pH during plasmid DNA handling steps, including ligation product clean-up and transformation-ready DNA prep.

Nucleic Acid Storage: Suitable for short-term storage of DNA and RNA to minimize acid hydrolysis and degradation.

Spectrophotometry and Standards: Used as a blank/diluent for A260/A280 measurements and preparation of quantification standards.

General Laboratory Buffer: Acts as a sterile, ready-to-use buffering solution for reagent preparation and sample handling where pH 8.5 is required.
