His-select nickel magnetic agarose beads

HIS-Select Magnetic Agarose Beads consist of paramagnetic, immobilized metal-ion affinity chromatography (IMAC) resin that contain a proprietary quadridentate chelate, which is bound with nickel and covalently attached through a non-charged, hydrophilic linker to magnetic beaded agarose. The magnetic properties of the beads aid in manipulations, such as repetitive washings, and recovery of the protein bound beads. This leads to greater experimental reproducibility and more accurate quantitation of the proteins of interest.
