Beskrivelse: Dimethyl Sulfoxide is ideal for use as a cryoprotectant. Also used in chemical reactions, in polymerase chain reactions (PCR) as a PCR cosolvent to help improve yields, especially in long 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). Used to enhance dermal absorption of many chemicals. A solvent for many organic and inorganic compounds including fats, carbohydrates, dyes, resins, and polymers. Used in antifreeze or hydraulic fluids. A cryopreservative for cell cultures. Used in the oxidation of thiols and disulfides to sulfonic acids.

Dimethyl sulfoxide (DMSO) is a highly polar aprotic organic reagent that has exceptional solvent properties for organic and inorganic chemicals.

Beskrivelse: Storage: Room Temperature, desiccate, store under nitrogen.
Dimethyl Sulfoxide is a dipola, aprotic solvent. It has been shown to accelerate strand renaturation (1-10% concentration) and is believed to give the nucleic acid thermal stability against depurination.
Dimethyl Sulfoxide is used to enhance dermal absorption of many chemicals, as a solvent for many organic and inorganic compounds including fats, carbohydrates, dyes, resins, and polymers, in antifreeze or hydraulic fluids, as a cryopreservative for cell cultures, oxidation of thiols and disulfides to sulfonic acids, as a PCR cosolvent to help improve yields, especially in long PCR. DMSO is routinely used in polymerase chan reaction (PCR), amplification of cDNA libraries, DNA sequencing, column-loading buffers for poly (A)+ RNA selection, buffers for the transformation of competent E. coli, and transfection protocols.
To prepare sterile solutions use a teflon or nylon membrane to sterile-filter the DMSO - do not use a cellulose acetate membrane.
