PureCube NTA (nitrilotriacetic acid) XL MagBeads were developed for IMAC-based protein purification and protein enrichment methods.

• Usage: For coupling of metal ions for corresponding purification and/or enrichment purposes
• Specificity: Varies
• Binding capacity: Depends on the loaded ion
• Purity: Depends on the loaded ion
• Bead Ligand: NTA
• Bead size: 90 μm
• Matrix: 6% cross-linked agarose
• Filling quantity: Delivered as a 25% suspension
• 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 90 µm. Since the affinity of an NTA-metal-ion-complex depends on the loaded metal ion, we offer NTA MagBeads uncoupled to any metal ion for the case that we do not offer your desired NTA and metal ion combination. Through our coupling protocol, you can, in turn, attach your desired metal ions to the agarose beads.
