ProBond™ Nickel-Chelating Resin is a nickel-charged affinity resin used to purify recombinant proteins containing a polyhistidine (6xHis) sequence. Proteins bound to the resin may be eluted with either low pH buffer or by competition with imidazole or histidine. One-step purification can be performed under both native and denaturing conditions. ProBond™ Resin uses the chelating ligand iminodiacetic acid (IDA) coupled to a highly cross-linked 6% agarose resin that is suitable for use in FPLC, batch, and gravity flow applications.
