Application

Dimethyl sulfoxide has been used:
  • for the dissolution of tetramethylrhodamine dye, which is used as fluorophore for fluorescence in- situ hybridization (FISH) experiments
  • as a control in indirect immunofluorescent assay (IFA) of swine testicular (ST) cells
  • for the suspension and separation of buccal cells
  • a polar aprotic solvent used in polymerase chain reactions (PCR) and as a cryoprotectant vitrification agent for the preservation of cells, tissues and organs.

Biochem/physiol Actions

Dimethyl sulfoxide (DMSO) is a low molecular weight, less hydrophilic and a freely permeable cryoprotectant. It is a polar aprotic solvent used in polymerase chain reactions (PCR) and as a cryoprotectant and vitrification agent for the preservation of cells, tissues and organs.
