General description

Aislamiento de la cromatina mediante purificación de ARN (ChIRP). Ci C Chu, Jeffrey J Quinn, Howard Y HY Chang, Journal of Visualized Experiments 2012-01-01
Aislamiento de la cromatina mediante purificación de ARN (ChIRP).

Los mapas genómicos de la ocupación del ARN no codificante largo revelan los principios de las interacciones ARN-cromatina.
Ci C Chu, Kun K Qu, Franklin L FL Zhong, Steven E SE Artandi, Howard Y HY Chang, Molecular Cell 2011-11-18Los mapas genómicos de la ocupación del ARN no codificante largo revelan los principios de las interacciones ARN-cromatina.
El alcohol etílico puro es un etanol no desnaturalizado de graduación 200. El etanol, un alcohol primario, es una materia prima importante para la síntesis de varios compuestos. Puede sintetizarse o bien a partir de melazas mediante fermentación o mediante hidratación del etileno. Actúa como una fuente de hidrógeno y como medio de reacción durante la hidrogenación de compuestos carbonilo por transferencia en presencia de hidróxido de sodio. Se ha estudiado el efecto de la fumigación de etanol o agua en el rendimiento de los motores diésel. Pueden utilizarse disolventes de calidad ACS para procesos que requieran condiciones de calidad estrictas, como las pruebas analíticas.
Los precios incluyen impuestos federales.
Nos hemos comprometido a proporcionarle los productos alternativos más sostenibles, que se adhieran a uno o más de los 12 principios de la química sostenible. El etanol es un disolvente ecológico medioambientalmente preferible y, por lo tanto, se alinea con los "Disolventes y auxiliares más seguros" y el "Uso de materias primas renovables".

  1. 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.

  2. 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.

  3. Who do I contact about larger solvent volume needs?

    Email us at labessentials@sial.com or visit Sigma-Aldrich Fine Chemicals for development and manufacturing-scale inquiries: safcglobal@sial.com

  4. How do I know what packaging options are available for a solvent?

    The Solvent Center gives you the ability to review all the specifications associated with our solvent packaging. This includes physical dimensions, closure types, dispensing methods, UN/DOT Rating as well as solvent compatibility. Visit the Solvent Center.

  5. Who do I contact if I need a solvent blend, which you do not carry?

    Email us at labessentials@sial.com. For a complete listing of all our Solvent blends, Visit the Solvent Center

  6. The dispensing of solvents provides some challenges due to the number of container options available. What dispensing options are available for each container?

    The Sigma-Aldrich Solvent Center provides numerous dispensing options for each container type. For a complete listing of all our dispensing options, Visit the Solvent Center.

  7. Which solvent grade should I be using for my application?

    Sigma-Aldrich Solvent Applications Table gives a guideline to common applications and the appropriate solvent grades.  Visit: Solvents

  8. What are the options for drying solvents? 

    Sigma-Aldrich offers a full range of high-purity solvents with extremely low water levels specifically manufactured for moisture sensitive Organic and Biotech applications.  Sigma-Aldrich also carries various drying agents such as molecular sieves, which are typically compatible with organic solvents.

  9. What apparatus do you recommend for HPLC solvent filtration?

    The Sigma-Aldrich Vacuum Filtration Assembly gives you all the components you need including: funnel top, fritted glass funnel support, filtration flask, aluminum clamp, and silicone stopper.  The Acrodisc Syringe Filters offer high quality filtration for analytical samples, certified for HPLC to ensure low extractable and available in a broad range of membranes to meet sample compatibility requirements.

  10. Can you recommend a Solvent Extractor for organics from aqueous solution?

    Solvent extractors are often used for the quantitative extraction of organics from aqueous solutions and separations in immunoassays. The MIXXOR system has been applied successfully in many laboratory solvent extraction operations and is ideal for the rapid screening of alternative solvents for specific extraction problems.

  11. What is 190 proof and 200 proof ethanol?

    All non-denatured ethanol products have a proof associated with the product description. The proof is a measure of the water content of the ethanol portion of the product. The proof is calculated as two times (2 x) the actual ethanol concentration by volume.

  12. How can I get help with the ATF paperwork for 190 and 200 proof ethanol?

    Because these non-denatured ethanol products are federally regulated, an ATF permit is required to purchase 190 and 200 proof ethanol. Sigma-Aldrich takes the hassle out of this process for you! There is no ATF paperwork needed or records to be kept on your part. Sigma-Aldrich holds the permit, and immediately pays the federal excise tax. For more regulatory information regarding the tax on ethanol, visit the U.S. Department of Justice, Bureau of Alcohol, Tobacco, Firearms and Explosives.

  13. 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.
