La estreptavidina T1 Dynabeads MyOne es el referente en el aislamiento y la manipulación de ácidos nucleicos biotinilados, anticuerpos u otros ligandos y objetivos biotinilados. La elevada afinidad de unión de la interacción entre estreptavidina y biotina (Kd = 10-15) se utiliza en un gran número de aplicaciones. Ventajas y características:

• Aislamiento rápido y directo de cualquier molécula biotinilada
• Protocolos flexibles con cinética de reacción de fase líquida suave y eficaz
• Microesferas de baja carga y neutras, óptimas para la unión de proteínas, péptidos y anticuerpos
• Su pequeño y uniforme tamaño ofrece una gran área de superficie por mg de microesferas y la consecuente gran capacidad para la molécula diana
• Baja tasa de sedimentación con un alto contenido de hierro, lo que garantiza una rápida separación magnética
• Protocolos biomagnéticos que se adaptan fácilmente a las plataformas automatizadas
• Alta reproducibilidad entre lotes que garantiza unos resultados uniformes en la aplicación

Acerca de la estreptavidina Dynabeads MyOne T1
Estas microesferas uniformes y superparamagnéticas poseen un diámetro de 1 μm, con una monocapa (y no una multicapa) de estreptavidina recombinante unida covalentemente a la superficie y bloqueada con BSA. La monocapa de estreptavidina hace que la gran mayoría de los sitios de unión de biotina estén disponibles estéricamente para la unión, no solo de biotina libre, sino también de ligandos y objetivos biotinilados. Las microesferas muestran una rápida cinética de reacción en fase líquida. Su superficie definida y específica permite disfrutar de una captura, separación y posterior manipulación de gran eficacia. La monocapa de estreptavidina garantiza unas fugas insignificantes, mientras que la ausencia de exceso de estreptavidina adsorbida garantiza la uniformidad de los lotes y la reproducibilidad de los resultados. Las microesferas Dynabeads MyOne de 1 μm tienen una gran superficie, una alta capacidad, una eficiente atracción magnética y una lenta tasa de sedimentación durante la incubación. Diseñados a medida para su uso en protocolos automatizados en los que un alto rendimiento es crucial.

Aplicaciones
En los últimos 15 años, las Dynabeads acopladas con estreptavidina se han empleado y citado para una gran variedad de aplicaciones. Entre las aplicaciones clave se incluyen la preparación de plantillas de ADN de una sola cadena, aislamiento de proteínas de unión de ARN y ADN, inmovilización de grandes fragmentos de ADN, purificación de productos de secuenciación y captura específica de ácidos nucleicos. Fácilmente adaptable a procesos automatizados. Dynabeads se emplea rutinariamente en más de 25.000 instrumentos de IVD en todo el mundo.

Capacidad de unión
El tamaño de la molécula y el procedimiento de biotinilación afectarán a la capacidad de unión. La capacidad depende también de la disponibilidad estérica y la interacción de la carga entre microesferas y moléculas y moléculas entre sí. Hay dos o tres sitios de unión de biotina disponibles para cada molécula de estreptavidina en la superficie de la microesfera después de la inmovilización. 1 mg de estreptavidina Dynabeads MyOne T1 normalmente une:

• 950–1500 pmol sin biotina
• ∼20 μg de IgG biotinilada
• ∼400 pmol de péptidos biotinilados
• ∼20 μg de ADNbc
• ∼400 pmol de oligonucleótidos de cadena simple

Preguntas frecuentes

Can Dynabeads Streptavidin magnetic beads be boiled?

We do not recommend this as streptavidin becomes hydrophobic and aggregates during denaturation.

I am getting high background using Dynabeads M-280 Streptavidin magnetic beads. How can I prevent this from happening?

The background might be caused by nonspecific binding to the BSA on the bead surface. Alternatively, high background might be caused by nonspecific binding to streptavidin. Increasing either the pH or the salt concentration might help reduce the binding. Dynabeads M-270 Streptavidin magnetic beads might be a better alternative; these beads are not coated with BSA and are hydrophilic, as they are based upon carboxylic acid chemistry.

My Dynabeads magnetic beads are not pelleting well with the magnet. Do you have any suggestions for me?

Please review the following possibilities for why your Dynabeads magnetic beads are not pelleting:

- The solution is too viscous.
- The beads have formed aggregates because of protein-protein interaction.

Try these suggestions: - Increase separation time (leave tub on magnet for 2-5 minutes)
- Add DNase I to the lysate (~0.01 mg/mL)
- Increase the Tween 20 concentration to ~0.05% of the binding and/or washing buffer.
- Add up to 20 mM beta-merecaptoethanol to the binding and/or wash buffers.

My Dynabeads M-280 Streptavidin magnetic beads were accidentally frozen. Can I still use them?

Yes, you can still use them. To test stability at low temperature in-house, the Dynabeads M-280 Streptavidin beads were placed at -20 degrees C for 24 hrs and then transferred to room temperature (15-25 degrees C) for 72 hrs. This freeze/thaw cycle was repeated 4 times and the beads were stored at 2-8 degrees C for 60 months. The biotin binding capacity was then tested and was seen to be within our specifications.

Which streptavidin-conjugated Dynabeads magnetic beads are the right beads for my application?

Which product to choose depends on the properties of your sample, the buffers and solutions applied, as well as the downstream application. In general, all Dynabeads Streptavidin beads can be used in applications involving biotinylated ligands; however, some beads may perform better than others in particular applications due to their characteristics. Dynabeads M-280 Streptavidin beads and Dynabeads MyOne Streptavidin T1 beads are commonly used for protein and nucleic acid applications. Dynabeads M-270 Streptavidin beads and MyOne Streptavidin C1 beads are preferred for nucleic acid diagnostics, specifically with samples that have a high concentration of chaotropic salts, immunoassays involving small biotinylated antigens, and in applications that are not compatible with BSA, as these beads are not blocked with BSA. Dynabeads MyOne Streptavidin beads offer increased binding capacity and slower sedimentation rate, making them ideal for automated applications and when larger amounts of a biotinylated compound or its specific target need to be isolated.
