Description

Application

N-Terminal histidine-tagged ubiquitin can replace native ubiquitin in formation of poly-ubiquitin—protein conjugates. The histidine tag enables separation and enrichment of protein conjugates on a Ni(II) column and detection of conjugates in western blot by anti-histidine-tag antibodies.
