The formaldehyde-sodium bisulfite adduct functions as a stabilizing agent in chemical reactions. It acts by reversibly binding to nucleic acids and proteins, preventing their degradation and preserving their structural integrity during experimental procedures. This adduct′s mode of action involves the formation of reversible covalent bonds with nucleophilic groups on biomolecules, thereby protecting them from damage caused by oxidation or other reactive species. The adduct can serve as a reducing agent, participating in redox reactions to maintain the reduced state of certain biomolecules. Its ability to stabilize and protect biomolecules makes it useful in experimental contexts involving the manipulation and analysis of nucleic acids and proteins.
