The quenching effect
Did you know?
In materials science, quenching is the rapid cooling of a workpiece in water, oil, polymer, air, or other fluids to obtain certain material properties. A type of heat treating, quenching prevents undesired low-temperature processes, such as phase transformations, from occurring. It does this by reducing the window of time during which these undesired reactions are both thermodynamically favor… Webb15 aug. 2024 · This strategy is based on the fact that the anti-m 6 A-antibody can specifically recognize and bind to the m 6 A site in the RNA sequence, resulting in a …
