General description

Features and Benefits:

  • Suitable for Molecular Applications
  • Nuclease-Free DMSO
  • DNase-Free, RNase-Free, Protease-Free, Phosphatase-Free
  • Molecular Biology Grade DMSO

Dimethyl sulfoxide (DMSO) is a highly polar organic reagent that has exceptional solvent properties for organic and inorganic chemicals.
This product is designated as Molecular Biology grade and is suitable for molecular biology applications. It has been analyzed for the presence of nucleases and proteases.

Application

DMSO (dimethyl sulfoxide) is a highly polar, aprotic organic solvent with many applications in organic chemistry and molecular biology. DMSO is routinely used in

  • polymerase chain reaction (PCR)
  • amplification of cDNA libraries
  • DNA sequencing
  • column-loading buffers for poly(A)+ RNA selection
  • buffers for the transformation of competent E. coli
  • transfection protocols.

Dimethyl sulfoxide has been used-

  • as an oligonucleotide solvent in array spotting[1]
  • as a solvent during miRNA microarray analysis and quantitative real-time PCR (qRT-PCR)
  • for cell lysis during MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay
  • for the preparation of the stock solution during MMP (mitochondrial membrane potential)cytofluorimetric assessment
  • in the storage of human and animal cell lines and bacteriophage λ as a cryoprotective agent.
To prepare a sterile filtered DMSO solution, it is recommended to use a PTFE or nylon membrane. Cellulose acetate membranes are not recommended.

Features and Benefits

This product is free from DNases, RNases, phosphatases and proteases.

Disclaimer

Supercools easily and remelts slowly at room temperature. Solidified product can be re-liquified by warming to room temperature without detriment to the product.

  5. I received Product D8418, Dimethyl sulfoxide, as a frozen solid. But isn't it supposed to be in the liquid state?

    1 answer
    1. 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.

      Helpful?

  6. What is the DMSO dissolved in?

    1 answer
    1. DMSO is not dissolved in any solvent. It is a pure chemical compound that is a liquid at room temperature.

      Helpful?

  7. Is Product D8418, Dimethyl sulfoxide, stable under extreme conditions?

    1 answer
    1. DMSO is stable up to 100°C in alkaline, acidic and neutral conditions. At temperatures approaching its boiling point, DMSO is stable in neutral or alkaline conditions.

      Helpful?

  8. How does the storage temperature relate to shipping conditions?

    1 answer
    1. 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.

  9. Does DMSO have any synthetic utility?

    1 answer
    1. 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.

      Helpful?

  10. Dimethyl sulfoxide (DMSO) should be a liquid.  Why did it arrive as a solid?

    1 answer
    1. 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.
