If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

General description
Más allá del análisis de proteínas, el SDS encuentra también aplicaciones en la separación electroforética de los lípidos, lo que permite el estudio y la caracterización de estos importantes componentes celulares. Además, el SDS se emplea en diversas técnicas de hibridación y biología molecular, lo que demuestra su versatilidad en una amplia gama de áreas de investigación. La eficacia del SDS tanto en condiciones iónicas como aniónicas amplía aún más su utilidad, permitiéndolo adaptarse a diversas configuraciones y requisitos experimentales. Su capacidad para desentrañar proteínas uniéndose a las cadenas peptídicas e impartiendo una carga negativa elimina eficazmente la forma de la proteína como un factor para la separación en el gel, lo que garantiza la determinación exacta del tamaño de la proteína.
Application
- en la immunoprecipitación de la cromatina
- en la electroforesis en gel SDS-poliacrilamida (SDS-PAGE)
- como componente de la disolución tampón del ensayo de radioinmunoprecipitación para inmunotransferencia
Features and Benefits
- Tensioactivo muy versátil para su investigación en biología molecular y bioquímica
- Adecuado para aplicaciones de electroforesis
- Confirmación probada de bajas concentraciones de contaminación por metales pesados,asegurando su idoneidad para diversas aplicaciones.

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
