PureCube Compact Cartridge Al-NTA
Order number: 31602-Al
Description
PureCube Al-NTA Compact Cartridge is an FPLC-ready column pre-packed with our PureCube Al-NTA agarose resin.
It is used for the purification of His-tagged proteins and the enrichment of phosphorylated proteins.
As an alternative, we also offer PureCube Al-NTA MagBeads, the more common format of Fe-NTA beads for phosphopeptide enrichment.
The PureCube cartridge/column that is used here is compatible with almost all commonly used FPLC systems like ÄKTA TM.

Lab Results
Automatic Phosphoproteomics for high-throughput projects
Fe-NTA magnetic beads by Cube Biotech have been proven to increase the speed of a high throughput experiment drastically. Leutert et al. (2019) presented the application of PureCube Fe-NTA MagBeads in a procedure that they named R2-P2, which is short for Rapid-Robotic PhosphoProteomics. They used a KingFisherTM Flex for their robotic runs to fully automize the phosphopeptide enrichment process.

Superiority over other phosphopeptide enrichment methods
Leutert et al. compared three different types of IMAC beads (including our PureCube Fe-NTA) and TiO2 microspheres. As it can be seen in figure 2 our PureCube Fe-NTA magnetic beads presented themselves to be the best option for phosphopeptide enrichment. With our Fe-NTA MagBeads the most unique phosphopeptides (Fig. 2 A and C) were enriched with the highest efficiency (Figure 2 B).

The best product for the best prize
Analyzing and comparing products from various manufacturers and suppliers can often prove to be a laborious task. The presence of varying concentrations and volumes across different suppliers can lead to confusion when trying to identify the optimal cost-benefit ratio. Recognizing these challenges, Cube Biotech has undertaken the effort to compile a comprehensive overview of prices for the frequently utilized phosphopeptide enrichment products (see Fig. 2 C). Our intention is to provide researchers with a clearer understanding of the prevailing pricing landscape in the market, facilitating informed decision-making.

FAQ
Can I get the datasheet for the Al-NTA Compact Cartridge?
The datasheet is not available as a PDF download on our site yet. But you can request it.
What can I do with Al-NTA beads?
Fe-NTA beads serve two purposes. First, they can be used as the matrix to bind and thus enrich phophopeptides. Second, they can be used similar to e.g Ni-NTA to purify His-tagged proteins via IMAC.
How does the phosphopeptide enrichment process work?
Use this protocol as a reference. It is written for our PureCube Fe-NTA MagBeads, so you have to make some adjustments to it.
Can I enrich all phosphopeptides using Al-NTA?
No, this is not possible. Not all phosphopeptides bind to Fe-NTA beads. As shown in figure 2 multiples bead types must be used to cover all phosphopeptides off a cell. Because of that we also offer Ti- Zr- and Al-NTA beads.
