PureCube Activated Agaroses XL


Affinity chromatography is typically done with agarose beads with particle sizes of 40-150 µm. This material is very well suited for gravity flow and FPLC applications.

Cube Biotech offers PureCube and PureCube 100 agaroses with a large variety of modifications that cover most applications.


However, for specialized experiments, agaroses with exceptionally large bead sizes (300-500 µm in diameter) can be useful. For example, large beads settle fast by gravity and are therefore useful for automated purification procedures. Please note that due to the significantly different surface:volume ratio, binding capacity is usually lower than for standard sized beads.


Activated Agaroses can be used to couple molecules of your choice in your laboratory. Our careful in-house production provides low lot-to-lot variation, making activated agaroses also suitable for commercial production.



PureCube Activated Agaroses XL provide:

  Pre-activated matrices for coupling to proteins, peptides, or antibodies

  Easy to follow protocols and expert technical support

  Highly reproducible synthesis in our own laboratories

  High throughput protein purification: Large beads settle fast in 96 well plates

  Compatible with the use of crude lysates



Activated Agaroses XL are available on request. Please contact us to learn more.
