Human anti Human cytokeratin 19/20 antibody recognizes human cytokeratin 20, and has been demonstrated to cross-react with cytokeratin 19. In immunohistology reactivity is seen both with tissues expressing only CK19 and with those expressing only CK20.

Human anti Human cytokeratin 19/20 antibody recognizes cytokeratins 19 and 20 as bands of ~40 kDa and ~45 kDa respectively by western blotting under reducing conditions.
