Nickel chelate resins recognize two exposed histidines for an appreciable retention of a protein and it is recommended in the majority of the cases. This resin works well with relatively easy to separate His-tagged proteins. Low Density Nickel has a lower amount of available groups that usually improve the selectivity/specificity.
