General description

Características y beneficios:

  • Adecuado para aplicaciones moleculares
  • DMSO sin nucleasas
  • Exento de ADNasas, ARNasas, proteasas y fosfatasas
  • DMSO calidad para biología molecular

El dimetilsulfóxido (DMSO) es un reactivo orgánico muy polar que tiene excepcionales propiedades disolventes para los compuestos químicos orgánicos e inorgánicos.
Este producto está designado como de calidad para biología molecular y es idóneo para aplicaciones de biología molecular. Se ha analizado la presencia o ausencia de nucleasas y proteasas.

Application

El DMSO (dimetilsulfóxido) es un disolvente orgánico muy polar aprótico con muchas aplicaciones en química orgánica y biología molecular. El DMSO se utiliza habitualmente en

  • la reacción en cadena de la polimerasa (PCR)
  • amplificación de los bancos de ADNc
  • secuenciación del ADN
  • disoluciones tampón para carga de columna para selección de ARN poli(A)+
  • tampones para la transformación de E.coli competente
  • protocolos de transfección

El dimetilsulfóxido se ha utilizado-

  • como disolvente de oligonucleótidos en la impresión de matrices (array spotting)[1]
  • como disolvente durante los análisis de micromatrices de miRNA y de la PCR cuantitativa en tiempo real (qRT-PCR)
  • para la lisis celular durante el ensayo del MTT (bromuro de 3-4,5-dimetiltiazol-2-il)-2,5-difeniltetrazolio)
  • para la preparación de la disolución de reserva durante la evaluación citofluorimétrica del potencial de la membrana mitocondrial (MMP)
  • en la conservación de líneas celulares humanas y animales, y de bacteriófagos λ, como crioprotector.
Para preparar una disolución de DMSO filtrada estéril se recomienda utilizar una membrana de PTFE o de nailon. No se recomiendan membranas de acetato de celulosa.

Features and Benefits

Este producto carece de ADNasas, ARNasas, fosfatasas y proteasas.

Disclaimer

Fácilmente superenfriado, vuelve a fundir lentamente a temperatura ambiente. Producto solidificado que puede volver a licuarse por calentamiento a temperatura ambiente sin detrimento del producto.
