General description
- Adapté aux applications moléculaires
- DMSO exempt de nucléases
- Exempt de DNases, de RNases, de protéases et de phosphatases
- DMSO de qualité "biologie moléculaire"
Le diméthylsulfoxyde (DMSO) est un réactif organique fortement polaire qui possède des propriétés de solvatation exceptionnelles vis-à-vis des composés chimiques organiques et inorganiques.
Ce produit, de qualité "biologie moléculaire", convient aux applications de biologie moléculaire. La présence de nucléases et de protéases a été recherchée dans ce produit, et leur absence a été confirmée.
Application
- L'amplification en chaîne par polymérase (PCR)
- L'amplification de banques d'ADNc
- Le séquençage de l'ADN
- Les tampons de charge de colonne pour la sélection d'ARN poly(A)+
- Les tampons destinés à la transformation de bactéries E. Coli compétentes
- Les protocoles de transfection
Le diméthylsulfoxyde a été utilisé :
- Comme solvant pour oligonucléotides pour la fabrication de puces (array spotting) [1]
- Comme solvant durant une analyse avec une puce à micro-ARN et en PCR quantitative en temps réel (qRT-PCR)
- Pour la lyse cellulaire durant un essai au MTT (bromure de 3-(4,5-diméthylthiazol-2-yl)-2,5-diphényltétrazolium)
- Pour la préparation de la solution mère nécessaire à une évaluation cytofluorimétrique du PMM (potentiel de la membrane mitochondriale)
- Comme agent cryoprotecteur pour la conservation de lignées cellulaires humaines et animales et de bactériophages λ

Dimethyl sulfoxide (DMSO) should be a liquid. Why did it arrive as a solid?
1 answer-
DMSO supercools easily, and re-melts slowly at room temperature. The melting point is 16-19 °C. The solidified product can be re-liquefied by warming to room temperature without detriment to the product.

I received Product D8418, Dimethyl sulfoxide, as a frozen solid. But isn't it supposed to be in the liquid state?
1 answer-
DMSO super cools easily and remelts slowly at room temperature. The product may arrive as a solid instead of a liquid. The solidified product can be reliquified by warming to room temperature without detriment to the product.
