Buffer Preparation: 1M Sodium Citrate, pH 5.0 provides precise acidic buffering for biochemical workflows and sample stabilization.

Enzyme Assays: Maintains optimal pH for acid-active enzymes (e.g., lysosomal hydrolases) using 1M Sodium Citrate, pH 5.0.

Nuclease/Protease Inhibition: Chelates divalent cations (Ca2+/Mg2+) to suppress nuclease and protease activity and to stop reactions.

Chromatography Buffers: Used as a citrate buffer in cation-exchange workflows and for gentle protein elution at pH 5.0.

DNA/RNA Extraction: Supports acidic lysis and stabilizes nucleic acids by metal ion chelation during purification.

Cell and Tissue Dissociation: Aids Ca2+/Mg2+ chelation for gentle cell detachment and tissue dissociation.

Antigen Retrieval (IHC): Serves as a citrate-based retrieval buffer for heat-induced epitope retrieval at acidic pH.

Microbiology Media Component: Provides citrate as a carbon source in utilization tests for organisms such as Klebsiella pneumoniae and Enterobacter aerogenes.

Blood/Plasma Processing: Used to prepare citrate-based anticoagulant or quench solutions by chelating calcium.

Dialysis and Storage: Maintains sample integrity at pH 5.0 during buffer exchange and short-term storage.
