Low Density Nickel
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.
