Uses: DMSO is a polar aprotic solvent used in chemical reactions, in polymerase chain reactions (PCR) and as a cryoprotectant vitrification agent for the preservation of cells, tissues and organs. DMSO is used in cell freezing media to protect cells from ice crystal induced mechanical injury. It is used for frozen storage of primary, sub-cultured, and recombinant heteroploid and hybridoma cell lines; embryonic stem cells (ESC), and hematopoietic stem cells. DMSO is frequently used in the combinations with BSA or fetal bovine serum (FBS).
Uses: Human and animal cell lines grown in culture are generally stored frozen. Freezing protects the cell line from changes due to genetic drift and minimizes risk of contamination. Liquid nitrogen used in conjunction with a cryoprotective agent such as DMSO is a widely used method for preserving cells. Without the presence of a cryoprotective agent, freezing is lethal to most mammalian cells. Damage is caused by mechanical injury by ice crystals, concentration of electrolytes, pH changes, and denaturation of proteins. These lethal effects are minimized by adding a cryoprotective agent which lowers
Uses: Dimethyl sulfoxide (1-10%) has been shown to accelerate strand renaturation and is believed to give the nucleic acid thermal stability against depurination. As a PCR cosolvent, DMSO may help improve yields, especially in long PCR.
Uses: A polar aprotic solvent used in polymerase chain reactions (PCR) and as a cryoprotectant vitrification agent for the preservation of cells, tissues and organs.
Uses: Suitable for HPLC, spectrophotometry, environmental testing
Uses: Solvent for many organic Compounds including fats, carbohydrates, dyes, resins, and polymers. In organic reactions. As antifreeze or hydraulic fluid when mixed with water. To cryopreserve and store cultured cells.
Pharmaceutical Applications: Dimethyl sulfoxide is a highly polar substance that is aprotic, therefore lacking acidic and basic properties. It has exceptional solvent properties for both organic and inorganic components, which are derived from its capacity to associate with both ionic species and neutral molecules that are either polar or polarizable. Dimethyl sulfoxide enhances the topical penetration of drug sowing to its ability to displace bound water from the stratumcorneum;this is accompanied by the extraction of lipids and configurational changes of proteins.
Industrial uses: Dimethyl sulfoxide, a product of an oxidation reaction on dimethyl sulfide, contains a very polar sulfoxide functional group. This highly polar functional group enables DMSO to form complexes with many metal ions, to act as a reaction medium for synthetic reactions, and to dissolve a large number of organic resins and polymers.
Storage: Dimethyl sulfoxide is reasonably stable to heat,but upon prolonged reflux it decomposes slightly to methyl mercaptan and bismethylthiomethane. This decomposition is aided by acids, and is retarded by many bases. When heated to decomposition, toxic fumes are emitted.
