Aplicación

El dimetilsulfóxido se ha utilizado:
  • en la preparación de bisfenol A (BPA)[1]
  • en ensayos de proliferación celular (ensayo de MTT)[2]
  • en ensayos de quimiosensibilidad[3]
  • como vehículo control en todos los experimentos como los análisis de apoptosis[4]

Acciones bioquímicas o fisiológicas

El DMSO (dimetilsulfóxido), un disolvente orgánico, posee diversas actividades farmacéuticas, tales como efectos analgésicos, diuréticos, bacteriostáticos, antiinflamatorios, vasodilatadores e inhibidores de la colinesterasa, además de capacidad para penetrar a través de la membrana.[6] Es un producto secundario de la industria maderera y se utiliza como un disolvente industrial. El DMSO sirve también como agente terapéutico para tratar la cistitis intersticial y la artritis.[7]

Questions

1–10 of 11 Questions  
  1. Can I use this product (suitable for plant cell culture) for cyropreservation of mammalian cells? Does cryopreservation of mammalian cells require sterile-filtered DMSO?

    1 answer
    1. D4540 is listed as suitable for cryopreservation.
      However, D2650 is already pre-sterile and has documentation with a protocol for cryopreservation of human and animal cell lines.

      See these links:
      https://www.sigmaaldrich.com/product/sigma/d2650
      https://www.sigmaaldrich.com/product/sigma/d2650#product-documentation

      Look for the Product Information Sheet. Also, see this link for more information:

  2. Can I autoclave this product?

    1 answer
    1. DMSO is not autoclavable in neat form. It is highly unlikely that microorganisms would survive in this environment. Should sterilization be necessary a PTFE, Polypropylene, or Nylon filter membrane are recommended for sterile-filtration.

  3. 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?

  4. Where does DMSO come from?

    1 answer
    1. DMSO is known to have been isolated from tree bark in the past. It is now a commericially synthesized solvent.

      Helpful?

  5. 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.

      Helpful?

  6. What is the molarity of DMSO?

    1 answer
    1. DMSO will have a molarity of 14.1M, based on a density of 1.1 g/mL and a molecular weight of 78.13 g/mol.

      Helpful?

  7. What concentration of DMSO do I use in a cell freezing media?

    1 answer
    1. DMSO is usually used at 1-10%, depending on the cell line.  For the cell freezing media that we offer, it is used at 8.7% concentration.

      Helpful?

  8. Is Dimethyl sulfoxide a sterile product?

    1 answer
    1. No, this product is not considered sterile.  Product Nos. D2560 and D2438 are sterile-filtered.

      Helpful?

  9. What type of filter is used to sterile-filter Dimethyl sulfoxide (DMSO)?

    1 answer
    1. DMSO can be sterile-filtered through a 0.2 micron PTFE filter. The sterility testing is per the current US Pharmacopoeia method.

      Helpful?

  10. 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.
