Protein Sample Preparation (SDS-PAGE/Western Blot): Reduces disulfide bonds in protein samples for SDS-PAGE and maintains reduced cysteines during electrophoresis and transfer.

Enzyme Stabilization and Assays: Preserves thiol-dependent enzymes by maintaining reducing conditions, preventing oxidative inactivation in enzyme assays.

Reverse Transcription and RT-qPCR: Enhances reverse transcriptase performance and protects RNA by reducing RNases during cDNA synthesis and RT-qPCR.

Protein Purification and Storage: Prevents disulfide-mediated aggregation during affinity and ion-exchange chromatography and in storage buffers.

Proteomics (Reduction/Alkylation): Reduces disulfide bonds prior to alkylation (e.g., iodoacetamide) for LC-MS sample prep.

Cysteine-Specific Labeling/Conjugation: Prerequisite reduction step for maleimide/iodoacetyl labeling of cysteine residues.

Glycoprotein Deglycosylation: Provides reducing conditions required for efficient PNGase F-mediated N-glycan removal.

Disulfide Mapping and Refolding Studies: Enables controlled reduction of disulfide bonds for structural analysis and refolding optimization.

RNA Workflows from Bacteria: Facilitates lysis and protects RNA during extraction from Escherichia coli and other bacteria.

CRISPR/Cas Protein Handling: Maintains Cas nucleases and guide RNPs in a reduced, active state during assembly and storage.
