These tubes should not be autoclaved prior to use, as we have not studied this for integrity. Tubes can be sanitized with 70% ethanol. However, the ethanol only sanitizes the device; it does not sterilize it.

General description
El diseño vertical y la superficie de membrana disponible proporcionan un procesamiento rápido de la muestra, una elevada recuperación de la muestra (normalmente superior al 90 % de la disolución inicial diluida) y la capacidad de concentración de 30 veces. La polarización del soluto y el consiguiente ensuciamiento de la membrana se reducen al mínimo gracias al diseño vertical, y un bloqueo físico del filtro evita la centrifugación hasta la sequedad y la posible pérdida de muestra. La recuperación eficiente de la muestra concentrada (especies retenidas) se consigue mediante una cómoda etapa de espín inverso después de recoger el filtrado.
Las unidades Amicon® Ultra-0,5 se suministran sin esterilizar y son para un solo uso. Con su diseño de membrana vertical y espín inverso, los filtros Amicon® Ultra de 0,5 ml ofrecen un gran rendimiento y menores tiempos de centrifugado.
Application
- Ultrafiltración con membrana Ultracel® de corte de peso molecular de 10 000 dalton
- Concentración de muestras biológicas que contienen antígenos, anticuerpos, enzimas, ácidos nucleicos o microorganismos
- Purificación de los componentes macromoleculares que se encuentran en extractos de cultivo tisular o lisados celulares, eliminación de cebadores, conectores o etiquetas macromoleculares de una mezcla de reacción y eliminación de las proteínas antes de la HPLC
- Desalación, cambio de la disolución tampón y diálisis de proteínas
Features and Benefits
- La membrana de celulosa regenerada Ultracel® con un NMWCO de 10 kDa proporciona una recuperación del retenido superior al 90 %
- Concentra desde 500 μl hasta 15 μl.
- Factor de concentración 25x a 30x
- Elevada recuperación de la muestra (superior al 90 % de la disolución diluida inicial)
- Tiempo de procesamiento rápido: 10 a 30 minutos
- La capacidad de espín inverso proporciona recuperaciones uniformes

Protocolos
Detergents are frequently used to solubilize proteins and nucleic acids during purification, but the presence of detergents may interfere with downstream analyses.
Best practices for standardizing and reducing the Extracellular Vesicle Preparation workflow, and eliminating contamination of EV preparations with dead-cell-derived vesicles.
If an antibody must be purified from a small sample volume (0.5-10 mL), then the Amicon® Pro Purification System is recommended.

Can I purchase just the flow through columns?
1 answer-
The Amicon Ultra products come in either 2 piece or 3 piece configurations. It is not possible to order just the filter inner tube or the empty outer tube. These two pieces fit together and are sold together as they are always needed. One sample, one centrifugal product. With the Amicon Ultra 0.5 or 2, we have a third piece, an outer collection tube added which is optionally used for reverse spin capability. Please consult our User Guide.

What is the minimum volume allowed by the device? If we have a volume of 50 microliters, is it advisable to dilute it in PBS to obtain a larger volume, closer to 500 microliters?
1 answer-
Diluting to 500 ul is optional. You have to consider what level of concentration is expected. Amicons can concentrate down to about 15 ul, so a 50 ul sample can only be concentrated ~3.3 fold.

What is the pore diameter of Amicon® Ultra Centrifugal Filter, 10 kDa
1 answer-
The ultrafiltration membrane in this product is characterized by a nominal molecular weight limit based on protein retention. An absolute linear pore diameter is not determined. However, a membrane with a 10 kDa molecular weight cutoff will retain nanoparticles of 3-9 nanometers. Please see the related article on nanoparticle ultrafiltration: https://www.sigmaaldrich.com/technical-documents/technical-article/analytical-chemistry/filtration/nanoparticle-ultrafiltration

What is the tolerance for molecular weight with these spin columns? Could you reasonably purify a protein of 15 kDa using these columns, or are the tolerances too high and would result in loss of protein into the filtrate?
1 answer-
It is recommended to choose a molecular weight cut-off that is at least two times smaller than the molecular weight of the target molecules.

If a centrifuge is unable to achieve a spinning speed of 14000 X g as recommended in the protocol, is it possible to compensate by spinning the samples for a longer duration?
1 answer-
Yes, it is possible to compensate for a lower centrifuge spinning speed by increasing the duration. This can be achieved by calculating the K factor, which determines the adjustment needed in time.
