1,4-Dithioerythritol (DTE) is widely used in biochemical and molecular biology research as a reducing agent. It helps in breaking disulfide bonds in proteins and peptides, aiding in the study of protein structure and function. DTE is also employed in electrophoresis techniques to maintain the reduced state of proteins, ensuring accurate analysis. Additionally, it is utilized in the preparation of samples for mass spectrometry, where it prevents oxidation and maintains sample integrity. In cell culture, DTE is sometimes used to protect cells from oxidative stress, promoting healthier growth conditions. Its ability to stabilize enzymes and other sensitive biomolecules makes it valuable in various laboratory applications.
