Protein Denaturation and Unfolding Studies: 7M Guanidine Hydrochloride acts as a chaotropic agent to unfold proteins for biophysical analysis (CD, fluorescence) and stability profiling.

Inclusion Body Solubilization and Refolding: Solubilizes aggregated recombinant proteins (e.g., from Escherichia coli) and supports refolding screens by controlled dilution or dialysis.

DNA/RNA Extraction and Purification: Facilitates lysis and nuclease inactivation while promoting nucleic acid binding to silica columns or magnetic beads for clean-up prior to PCR/RT-qPCR.

Cell and Tissue Lysis: Disrupts bacterial (Escherichia coli), yeast, and mammalian samples to release proteins and nucleic acids under denaturing conditions.

Nuclease and Protease Inactivation: Inactivates RNases/DNases and proteases to preserve integrity of biomolecules during sample preparation.

Protein Purification Under Denaturing Conditions: Enables IMAC/Ni-NTA and other chromatography workflows requiring denaturants to purify difficult or aggregated proteins.

Viral and Microbial Inactivation for NAAT: Inactivates pathogens while stabilizing nucleic acids for downstream diagnostic extraction and amplification.

Proteomics Sample Preparation: Denatures proteins prior to reduction/alkylation; samples are subsequently diluted for enzymatic digestion and LC–MS/MS analysis.

PCR Template Clean-Up: Used in chaotrope-based clean-up to remove inhibitors and prepare DNA for amplification.

Prevention of Protein Aggregation: Maintains proteins in a solubilized state during purification and storage optimization studies.
