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

-
How does the storage temperature relate to shipping conditions?
1 risposta-
The storage conditions that a Sigma-Aldrich catalog and label recommend for products are deliberately conservative. For many products, long-term storage at low temperatures will increase the time during which they are expected to remain in specification and therefore are labeled accordingly. Where short-term storage, shipping time frame, or exposure to conditions other than those recommended for long-term storage will not affect product quality, Sigma-Aldrich will ship at ambient temperature. The products sensitive to short-term exposure to conditions other than their recommended long-term storage are shipped on wet or dry ice. Ambient temperature shipping helps to control shipping costs for our customers. At any time, our customers can request wet- or dry-ice shipment, but the special handling is at customer expense if our product history indicates that the product is stable for regular shipment.

Does DMSO have any synthetic utility?
1 risposta-
DMSO has been used to oxidize thiols and disulfides to sulfonic acids, hydrolysis of epoxides, thioalkylation of phenols, and oxidation of primary alcohols and halides, and esters of primary alcohols to aldehydes.
