1-Thioglycerol is widely used in biochemical and molecular biology research as a reducing agent to maintain the stability and functionality of proteins and enzymes. It helps prevent the oxidation of thiol groups, ensuring the proper folding and activity of proteins during experiments. In cell culture applications, it acts as a supplement to enhance cell growth and viability by reducing oxidative stress. Additionally, it is employed in the preparation of electrophoresis gels to break disulfide bonds in proteins, enabling accurate analysis of molecular weights. Its role as a stabilizer in pharmaceutical formulations also ensures the efficacy and shelf life of certain drugs.
