dimethyl sulphoxide การใช้

Understanding of the nature of aqua ions is helped by having information on the nature of solvated cations in mixed solvents and non-aqueous solvents, such as liquid ammonia, methanol, dimethyl formamide and dimethyl sulphoxide to mention a few.
To minimize the growth of extracellular ice crystal growth and recrystallization, biomaterials such as alginates, permeability : a typical cooling rate of about 1 癈 / minute is appropriate for many mammalian cells after treatment with cryoprotectants such as glycerol or dimethyl sulphoxide, but the rate is not a universal optimum.
In Escherichia coli, the anaerobic expression of genes encoding the nitrate ( narGHJI ) and dimethyl sulphoxide ( dmsABC ) terminal reductases is stimulated by the global anaerobic regulator-FNR . The ability of FNR to activate transcription initiation has been proposed to be dependent on protein protein interactions between RNA polymerase and two activating regions ( AR ) of FNR, FNR-AR1 and FNR-AR3 . Also, in the presence of activated narL, the effect of FNR binding to the RNAP is decreased greatly.
