High density nickel-iminodiacetic acid (IDA) crosslinked agarose resin for low pressure affinity chromatography. The high amount of available nickel chelate groups allows for high binding capacity. Nickel chelates recognize two exposed histidine tags with high specificity and very high affinity. Therefore a nickel charged matrix is recommended for most standard purifications. Suitable for batch or column purifications. Binding/loading capacity: 20 - 40 µmol Me2+/ml gel.
