Dimethyl Sulfoxide Uses
- DMSO (dimethyl sulfoxide) is a highly polar, aprotic organic solvent with numerous applications in organic chemistry and molecular biology. DMSO is routinely used for polymerase chain reaction (PCR), amplification of cDNA libraries, DNA sequencing, column loading buffers for poly(A)+ RNA selection, and for competent E. coli transformation and transfection experimental methods. buffer.
- Dimethyl sulfoxide has been used for –
- Oligonucleotide Solvents in Array Blots
- Solvents in miRNA Microarrays and Quantitative Real-Time PCR (qRT-PCR)
- Cell lysis in MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay
- Preparation of stock solutions for MMP (mitochondrial membrane potential) cytofluorescence assessment
