Although antibodies can be useful in protecting you against various illnesses, they're not the only component that's key to preventing reinfection, either. Lyophilization involves drying antibodies at a very low temperature, reducing the damage to the products and retaining the molecular integrity. The active ingredients of ProClin 300 are 5-chloro-2-methyl-4-isothiazolin-3-one (CMIT) and 2-methyl-4-isothiazolin-3-one (MIT), inhibitors of Kreb cycle enzymes -ketoglutarate dehydrogenase, succinate dehydrogenase, and NADH dehydrogenase.
