PureCube NTA (nitrilotriacetic acid) XL agarose resin was developed for IMAC based protein purification and protein enrichment methods. Since the affinity of an NTA-metal-ion-complex depends on the loaded metal ion, we offer NTA XL agarose resin uncoupled to any metal ion for the case that we do not offer your desired NTA + metal ion combination. By providing our coupling protocols, feel free to create any NTA purification resin you desire. PureCube NTA resin is also available in regular bead sizes with a bead diameter of 40 µm and 100 µm sized . Alternatively we also offer NTA magnetic beads. Furthermore PureCube NTA agarose (40 µm) can also be obtained pre-filled into FPLC cartridges / columns.
