HCA041A recognises human cytokeratin 20, and has been demonstrated to cross-react with cytokeratin 19.
In Western blotting of of HT29 cell lysates two bands are seen, one at 40kD being consistent with CK19, and one at 45kD being consistent with CK20.
In Immunohistology reactivity is seen both with tissues expressing only CK19 and with those expressing only CK20.
Product Form
