General description
- adatto per applicazioni di biologia molecolare
- DMSO privo di nucleasi
- Privo di DNasi, RNasi, proteasi e fosfatasi
- DMSO per biologia molecolare
Il dimetilsolfossido (DMSO) è un reagente organico altamente polare con eccezionali proprietà solventi sia nei confronti delle sostanze organiche, sia di quelle inorganiche.
Questo prodotto è di grado “Biologia molecolare” e quindi adatto per applicazioni di biologia molecolare. E′ stato testato per la presenza di nucleasi e proteasi.
Application
- la reazione a catena della polimerasi (PCR)
- l′ amplificazione di librerie di cDNA
- il sequenziamento del DNA
- il tampone di caricamento per colonna per l′isolamento di RNA con coda di poli A (poli (A) + RNA)
- il tampone per la trasformazione di E. coli competenti
- nei protocolli per la trasfezione
Il dimetilsolfossido è utilizzato:
- come solvente degli oligonucleotidi negli spotted microarrays[1]
- come solvente durante l'analisi di microarray di miRNA e nella real-time PCR quantitativa (qRT-PCR)
- per la lisi cellulare durante il test MTT (3-(4,5-dimetiltiazol-2-il)-2,5-difeniltetrazolio bromuro)
- per la preparazione della soluzione madre durante la valutazione citofluorimetrica del MMP (potenziale di membrana mitocondriale)
- come crioprotettore nella conservazione di linee cellulari umane e animali e di batteriofagi λ congelati

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.
