Zinc chelates seem to recognize well two exposed histidine tags in vicinal position. This kit is recommended for proteins that are difficult to separate. It includes: 2ml of HIGH Density ZINC, 2ml of LOW Density ZINC and 20 empty mini-columns to allow for centrifugation steps during the procedure. HIGH Density ZINC provides a higher amount of available groups and usually allows for higher binding capacity. LOW Density ZINC has a lower amount of groups and it usually improves the selectivity/specificity.
