Why you are using 2 mercaptoethanol in mes cell culture?

Mercaptoethanol is a thiol compound that is involved in the reduction of substances and prevents the oxidation of cysteine to cystine, thus increasing cysteine activity. It acts as an antioxidant by itself and indirectly by increasing intracellular gluthathione and cysteine activity


Role of beta mercaptoethanol on enzyme activity?

Beta Mercaptoethanol disrupts the sulfide bonds of most enzymes. The portion of enzyme that withstands Beta Mercaptoethanol will bind less SDS, which ultimately leads to anomalous migration of the substrate through the electrophoresis gel.
