At the time the User Guide was written, 100 mM was the highest concentration tested. Subsequent testing has been conducted with concentrations as high as 300 mM. Higher concentrations of imidazole are not recommended for concentration. Using imidazole concentrations above 100 mM is not expected to damage the device; however, high salt solutions, including imidazole, may lead to sub-optimal results. Sub-optimal results can include slower flow rates, poorer recovery, and increased detection background or interference in model systems.

Description générale
Leur configuration verticale et leur surface utile de filtration en font des dispositifs très performants : traitement rapide, très bon taux de récupération (en général plus de 90 % de la solution de départ diluée) et possibilité de concentrer l'échantillon 80 ×. Leur configuration verticale permet en outre de minimiser la polarisation du soluté, et donc, le colmatage de la membrane qui en découle. Enfin, la présence d'une butée physique à l'intérieur du dispositif empêche d'atteindre la siccité tout en prévenant les éventuelles pertes d'échantillon.
Le concentré est récupéré dans le réservoir à échantillon du filtre à l'aide d'une pipette, tandis que l'ultrafiltrat est recueilli dans le tube à centrifuger fourni. Le filtre peut être centrifugé dans un rotor à godets oscillants ou à angle fixe. Avec leur membrane verticale et leur butée fixe, les filtres à centrifuger Amicon® Ultra de 15 ml offrent un taux de récupération maximal pour un temps de centrifugation relativement court.
Application
- Ultrafiltration sur membrane Ultracel® à seuil de coupure de 100 000 Da
- Concentration d'échantillons biologiques contenant des antigènes, des anticorps, des enzymes, des acides nucléiques ou des micro-organismes
- Purification des composants macromoléculaires présents dans des extraits de culture tissulaire ou des lysats cellulaires et élimination des protéines avant chromatographie liquide haute performance
- Concentration de protéines diluées ou prépurifiées à partir d'éluants de colonne
- Dessalage, échange de tampon et dialyse des protéines
Caractéristiques et avantages
- Membrane Ultracel® en cellulose régénérée à seuil de coupure nominal de 100 kDa offrant une récupération du rétentat supérieure à 90 %
- Réduction de la polarisation de la concentration grâce à la membrane verticale, pour des temps de centrifugation ultrarapides (à peine 10 à 15 minutes)
- Membrane thermoscellée minimisant les quantités de matières extractibles en aval
- Tests d'intégrité réalisés sur 100 % des filtres pour garantir la fiabilité des résultats
- Visualisation pratique de l'échantillon grâce au tube translucide et aux graduations de volume
- Pipetage direct de l'échantillon (suppression de l'étape de récupération du concentré)
- Facteurs de concentration élevés (80 × à 100 ×)

I see the device is only compatible less than 100 mM imidazole. However the his-tagged protein usually washed higher than 100 mM imidazole. what will happen if it is used to concentrate sample with imidazole higher than 100 mM?

Filters with smaller (MWCO) values (3K/10K) tend to produce a higher filtrate volume in a shorter time compared to those with larger MWCOs (e.g., 100K).Why do filters with smaller MWCOs appear to elute faster, even though they have smaller pore sizes?
1 réponse-
Each liquid being concentrated in centrifugal devices, each type of substance in the liquid, each amount of particles in a liquid, and each initial volume, type of size, and surface area of a device is unique. Centrifuges are spun at a specific speed based on which type of centrifuge is being used. Therefore, there are many variables involved in the reduction of volume from one initial volume to another, and thus, the end result of the time it takes to reduce volume is different. We as a vendor cannot comment on a customer's specific observation and final result explaining volume reduction and time of a sample.

The product comes with the tube and filter as one piece. Is this correct? how can i get under 100kDa liqud?

Temperature limit?
1 réponse-
The Amicon Ultra devices are rated for Room Temperature environments and "normal laboratory conditions". We have not studied a set limit but do know that if stored in a warehouse at higher temperatures and humidities, the devices can be affected.

Is it reusable? How many times I can fill it up again? Amicon Ultra 15. First time I fill it up with 15 ml, and after can I use it again for other 15 ml....and again?
1 réponse-
The Amicon Ultra 15 is designed for single use but can be used for repeated spins with the same sample. However, repeated use will cause clogging of the membrane, leading to slower flow rates and longer spin times.

Hello, Are these tubes valid for AAV concentration? And if so, are these valid for all serotypes? Also, the user guide says that the membrane's material is 'Ultracel® low binding regenerated cellulose'. What's the difference with the PES membrane?
1 réponse-
These devices can be used for virus concentration but are not validated for any specific type. Both PES and regenerated cellulose membranes have low binding, but PES has a faster flow rate. For more information, please refer to the technical article on the website: https://www.sigmaaldrich.com/technical-documents/technical-article/analytical-chemistry/filtration/viral-concentration-amicon-ultrafiltration

Hi, I have plan to use the Amicon Ultra-15 100K for Exosome extraction from cell culture supernatant, could you please let me know what would be the best speed (rpm/rcf) and time for doing that? Thanks
1 réponse-
Typically, Amicon-15 devices are spun at 4,000 x g (relative centrifugal force) for exosome isolation. However, spin times may need to be optimized, based on the sample type and volume. The image below demonstrated the relationship between volume and spin times. Please see the link below to review the product User Guide. More specific spin time information is available on page 3.

What is the minimum starting volume I can load on Ultra 100K (100,000 MWCO) devices? Can I load as little as 500 µL?
1 réponse-
This product is intended for use with 4-15 mL initial sample volumes. The device has not been evaluated for use with volumes smaller than those recommended. While it may be possible to concentrate samples as low as 500 uL, the recovery volume cannot be predicted. Please see the link below to review an alternative Amicon device specifically designed for 500 uL samples.

Does the Amicon Ultra has residues that may released into the concentrated product', like Beta-Glucan?
1 réponse-
These devices contain trace amounts of glycerine. If this material interferes with downstream analysis, rinse the device with buffer or Milli-Q® water prior to use. Should interference continue, rinse with 0.1 N NaOH followed by a second spin of buffer or Milli-Q® water. NOTE: Do not allow the membrane to dry out following rinse steps. If the product will not be used immediately after rinsing, leave the final buffer or water on the membrane until the usage. Please see the link below to review the full product User Guide:
