Description and Uses
2-Mercaptoethanol is used in the preparation of nano-graphene for cellular imaging and drug delivery as well as multifunctional polymeric micelle. It acts as a reducing agent used in electrophoresis, amino acid detection, and distinguishing ssDNA/dsDNA. It is also employed as a standard buffer. It is also used in the preparation of PVC heat stabilizers and as a chain transfer agent in the manufacture of PVC. Further, it is used in some RNA isolation procedures to eliminate ribonuclease. It is utilized as a corrosion inhibitor and ore floatation agent. In biochemistry, it is useful to study the activity of the immune system. Solubilizes proteins by reducing disulfide linkages.
