Widely used as a reducing agent in biochemistry and molecular biology, it effectively breaks disulfide bonds in proteins and peptides, facilitating their study and manipulation. It is particularly valuable in protein purification and characterization processes, where maintaining the reduced state of cysteine residues is crucial. Additionally, it is employed in the preparation of samples for mass spectrometry, ensuring accurate analysis of protein structures. Its stability and water solubility make it a preferred choice in various laboratory applications, including the reduction of antibodies for conjugation with fluorescent dyes or enzymes.
