Dab tsi yog dimethyl sulfoxide siv rau hauv chav kuaj?
Dimethyl sulfoxide (DMSO)Feem ntau yog siv nyob rau hauv lub chaw soj nstuam raws li hnyav, permeant, thiab cov tshuaj tiv thaiv nruab nrab, nrhiav kev siv dav hauv tshuaj synthesis, cell culture, analytical chemistry, thiab lwm yam.
Solvent Function
- Siab polarity thiab solubility: DMSO dissolves ntau cov organic thiab inorganic tebchaw, nrog rau biomacromolecules (xws li, DNA, proteins), ua rau nws tsim nyog rau kev npaj siab - concentration daws.
- Chromatography: Ua haujlwm raws li theem nyob ruaj khov hauv roj chromatography lossis hnyav rau UV spectroscopy.
Penetrant Function
- Kev xa tshuaj: Txhim kho kev nkag mus los ntawm cov cell membranes, feem ntau siv hauv kev tshawb fawb tshuaj permeability thiab genetic engineering.
- Cell Culture: Ua hauj lwm rau cryopreserving hlwb los yog dissolving tshuaj reagents.
Tshuaj Reaction Medium
- Organic Synthesis: Accelerates cov tshuaj tiv thaiv zoo li electrophilic hloov pauv thiab ester pauv, txhim kho yields.
- Polymerization Reactions: Ua ib qho hnyav rau acrylonitrile polymerization lossis hauv cov khoom sib txuas xws li polyurethanes thiab polyimides. cov
Lwm Daim Ntawv Thov
- Antioxidant thiab Anti-inflammatory: Txo oxidative puas thiab inflammatory teb los ntawm inhibiting dawb radicals los yog tswj leukocyte migration.
- Pesticide Synthesis: Ua raws li kev nkag mus lossis cov tshuaj tiv thaiv hnyav los txhim kho kev ua kom zoo ntawm cov tshuaj tua kab thiab tshuaj tua kab. cov
