General description

EL reactivo TRI® es un reactivo rápido y cómodo listo para usar, útil para la extracción eficaz del ARN total o para el aislamiento simultáneo de ARN, ADN y proteínas. EL reactivo TRI® es una mezcla de tiocianato de guanidina y fenol en una disolución monofásica.
La homogeneización o lisis de la muestra de tejido en el reactivo TRI® disuelve el ARN, el ADN y las proteínas. La adición de cloroformo o 1-bromo-3-cloropropano seguida de centrifugación produce la separación en tres fases: una fase acuosa que contiene el ARN, la interfase que contiene el ADN y una fase orgánica que contiene las proteínas. A continuación, puede aislarse cada uno de los componentes después de separar las fases.

Application

El reactivo TRI se ha utilizado:
  • en el aislamiento del ARN total de varias muestras de tejido y células [1][2][3][4]
  • para la lisis de monocitos [5]
  • para aislar el ARN citoplasmático de las células Vero infectadas por el SARS-CoV [6]
  • para aislar el ARN total de MDM (macrófagos derivados de monocitos) infectados por el virus de la gripe A (H5N1) [7]
  • para preparar un lisado vírico de cultivo de SARS-CoV con objeto de crear un clon que codifique la glucoproteína S en el desarrollo de la vacuna contra el SARS-CoV [8]

El ARN, el ADN y las proteínas que se aíslan con el reactivo TRI® pueden utilizarse para aplicaciones posteriores, como clonación, PCR, RT-PCR, aislamiento del ARNm, traducción in vitro, ensayo de protección de ARNasas, digestión con enzimas de restricción, SDS-PAGE y técnicas northern, Southern y Western.
El reactivo TRI es una versión mejorada del reactivo de aislamiento del ARN total en una etapa desarrollado por Chomczynski. El método de aislamiento del ARN basado en este reactivo es ampliamente utilizado y probado para aplicaciones del ARN. Es ideal para el aislamiento rápido, económico y eficiente del ARN total o el aislamiento simultáneo del ARN, el ADN y las proteínas de muestras de origen humano, animal, vegetal, de levaduras, bacteriano y vírico.

Features and Benefits

Facilidad de uso: Un único reactivo que puede utilizarse para el aislamiento de ARN, ADN y proteínas sin contaminación.
Multiuso: el rendimiento del reactivo TRI® es bueno con cantidades grandes o pequeñas de tejido o células; el reactivo funciona con muchos tipos de muestras, como las humanas, vegetales, bacterianas, víricas y de levaduras.
Eficiencia: el reactivo TRI® proporciona mejores rendimientos que los métodos tradicionales de tiocianato de guanidina o cloruro de cesio. El proceso completo de extracción del ARN desde el tejido o las células frescas, puede completarse en menos de una hora.
  • Aislamiento del ARN fácilmente escalable
  • Funciona con muchos orígenes: humano, vegetal, levaduras, bacterias o vírico
  • Mejor rendimiento que los métodos tradicionales de tiocianato de guanidina/cloruro de cesio

Questions

1–10 of 10 Questions  
  1. what is the size(kb) of the trizol extracted DNA?  

    1 answer
    1. This product is intended to simply maintain the integrity of the DNA and RNA during extraction and does not play a role in the disruption or digestion of the sample. Both, large and small nucleic acid molecules will be recovered. The primary factor in determining the size of the recovered nucleic acid fragments will be the method utilized to disrupt the cells or tissues.

  2. Using trizol in isolation gDNA from nuclei (from plant). After extracting nuclei, pellet(nuclei) is dissolved in 1.6-6.4mL TE buffer and incubated with SDS and Proteinase K. Next is trizol, what is the ratio of trizol to add to this liquid sample?

    1 answer
    1. As mentioned in the product bulletin, "the volume of the tissue should not exceed 10% of the volume of the TRI Reagent." For a sample volume range of 1.6 ml to 6.4 ml, you would need to add a minimum of 16 ml to 64 ml of Tri Reagent.
      Please see the link below for more information: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/product/documents/294/543/t9424bulletin.pdf

  3. Does trizol have SDS in it?

    1 answer
    1. As mentioned in the 'DESCRIPTION' section under 'General Description', TRI reagent® is a mixture of guanidine thiocyanate and phenol in a monophasic solution. This product does not contain SDS.

  4. How long can samples be stored in TRI Reagent at -80°C?

    1 answer
    1. Prior to phase separation, TRI Reagent-treated tissue extracts can be stored at -80 °C for years without demonstrable negative effects on
      recovered RNA quality or quantity. Although salt precipitation following freezing has not been observed, the investigator must make sure that any
      salts that may precipitate from the solution during the freeze-thaw cycle are resolubilized before using proceeding.

  8. Which chloroform and isopropanol do you recommend to be used with T9424, Tri Reagent™?

    1 answer
    1. For chloroform and isopropanol we recommend C2432 and I9616, respectively.

  9. If I add a volume of Product T9424, Tri Reagent™, different from 1 ml, how much chloroform and isopropanol should I add?

    1 answer
    1. What is important is to keep the ratio the same. For example, we recommend adding 200 μL of chloroform and 500 μL of isopropanol when using 1 ml of Tri Reagent. Therefore, 100 μL of chloroform and 250 μL of isopropanol would be added if using 500 μL of Tri Reagent. Similarly, 300 μL of chloroform and 750 μL of isopropanol would be added to if using 1.5 ml of Tri Reagent.

      Helpful?

  10. What is the expiration date for Product T9424, Tri Reagent™?

    1 answer
    1. The expiration date for T9424 has not been established. However, based on our storage guidelines, it should be usable for 1 year from the date of receipt.
