• Matrix: 7.5% cross-linked agarose
• Filling quantity: Delivered as a 50% suspension
• Recommended FPLC flow rates: 0.5 to 2 ml/min
• Maximal FPLC flow rate: 6 ml/min
• pH stability: 2 to 14
• Other stabilities: 100% methanol, 100% ethanol, 8 M urea, 6 M guanidinium hydrochloride, 30% (v/v) acetonitrile

The beads in this suspension have an average diameter of 40 µm and, thus, excellent mechanical stability. Since the affinity of an IDA-metal-ion-complex depends on the loaded metal ion, we offer IDA agarose resin uncoupled to any metal ion in case we do not offer your desired IDA + metal ion combination. Through our coupling protocol, you can, in turn, attach your desired metal ions to the agarose beads. PureCube IDA resin is also available with a bead diameter of 400 µm for higher FPLC flow rates or as IDA magnetic beads. Furthermore, PureCube IDA agarose is also obtainable pre-packed into FPLC cartridges/columns.
