General description
- Geeignet für molekulare Anwendungen
- Nuklease-freies DMSO
- DNasefrei, RNasefrei, Proteasefrei, Phosphatasefrei
- DMSO für die Molekularbiologie
Dimethylsulfoxid (DMSO) ist ein hochpolares organisches Reagenz, das über außergewöhnliche Lösungsmitteleigenschaften für organische und anorganische Chemikalien verfügt.
Dieses Produkt ist als molekularbiologisches Reagenz klassifiziert und ist für molekularbiologische Anwendungen geeignet. Es wurde auf das Vorhandensein von Nukleasen und Proteasen hin analysiert.
Application
- Polymerase-Kettenreaktion (PCR)
- Amplifikation von cDNA-Bibliotheken
- DNA-Sequenzierung
- Säulen-Ladepuffer für die Poly(A)+ RNA-Selektion
- Puffer für die Transformation kompetenter E. coli
- Transfektionsprotokolle
Dimethylsulfoxid wird verwendet:
- als Lösungsmittel für Oligonukleotide beim Array-Spotting[1]
- als Lösungsmittel bei der miRNA-Microarray-Analyse und der quantitativen Echtzeit-PCR (qRT-PCR)
- für die Zelllyse während des MTT (3-(4,5-Dimethylthiazol-2-yl)-2,5-Diphenyltetrazolium-Bromid)-Assays
- für die Herstellung der Stammlösung während der zytofluorimetrischen Bewertung des MMP (mitochondriales Membranpotential)
- bei der Lagerung menschlicher und tierischer Zelllinien und Bakteriophage λ als Kryoprotektor.

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.
