Application

El dietilpirocarbonato se ha utilizado en la reacción de PCR para tratar el agua desionizada, lo que reduce el riesgo de que el ARN sea degradado por las RNasas. También se utiliza para la hibridación por puntos, para diluir el ARN aislado de los diferentes microorganismos.
Reactivo de modificación para residuos de His y Tyr en proteínas. Sonda robusta para alteraciones estructurales en el ADN bicatenario, que reacciona con las bases total o parcialmente desapiladas.

Biochem/physiol Actions

El DEPC es un potente inhibidor de nucleasas.Se utiliza una disolución al 0,1% de DEPC para inactivar la RNasa.
Inhibe la rianodina uniéndose a los receptores de rianodina/canales de Ca2+ en el músculo esquelético de una manera dependiente de la dosis y del tiempo, y aumenta la permeabilidad al Ca2+ de las vesículas SR.
Inactiva la ARNasa en disolución aproximadamente al 0,1% (v/v). Por tanto, protege el ARN contra la degradación.

General description

El dietilpirocarbonato (DEPC) es un compuesto químico que se utiliza para inactivar las enzimas RNasas y es sensible a la humedad y el pH. Se descompone a 155°C a etanol y dióxido de carbono en disolución acuosa. El DEPC es también sensible al amoniaco, que provoca su descomposición a uretano, un posible carcinógeno.

  1. What is the stability of Product D5758, Diethyl pyrocarbonate, at room temperature?

    The material is stable at room temperature as long as it is protected from moisture.  We do recommend 2-8 °C for its storage.

  2. How can I tell if Product D5758, Diethyl pyrocarbonate, has degraded?

    DEPC breaks down to ethanol and carbon dioxide.  The carbon dioxide builds up pressure inside the bottle; when opened, it will degas and/or bubble out of the bottle.

  3. What buffers can I use with Product D5758, Diethyl pyrocarbonate (DEPC)?

    DEPC reacts with amines, thiols, and alcohols.  Any buffer that contains an amine, e.g.., Trizma, should not be used.  View this information on the product information sheet (under Documents, above.

  4. What type of container should I use to handle Product D5758, Diethyl pyrocarbonate (DEPC)?

    Glassware is preferable since some plastics, e.g.., polycarbonate, are known to react with DEPC.

  5. Why is stirring or shaking necessary when making RNAse-free water for use with Product D5758, Diethyl pyrocarbonate?

    DEPC is not very soluble in water. Stirring and/or shaking is necessary to suspend DEPC in water.

  6. What is the best way to use Product D5758, Diethyl pyrocarbonate, to inactivate RNAse?

    Add DEPC directly to the water to yield a 0.1 % solution.  Shake vigorously and allow to set overnight at room temperature with the lid loose or incubated for 2 hours at 37 °C.  The solution is then autoclaved 15 minutes for each liter.

  7. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  8. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  9. How do I find price and availability?

    There are several ways to find pricing and availability for our products. Once you log onto our website, you will find the price and availability displayed on the product detail page.
