애플리케이션
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.
생화학적/생리학적 작용
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.
주의사항
Supercools easily and remelts slowly at room temperature. Solidified product can be re-liquified by warming to room temperature without detriment to the product.
