Example
AE1/AE3
AE1 reacts with acidic (type-I) cytokeratins—high molecular weight cytokeratins 10, 14, 15 and 16, and low molecular weight CK19—while AE3 reacts with all known basic (type-II) cytokeratins— high molecular weight cytokeratins 1, 2, 3, 4, 5 and 6, and low molecular weight cytokeratins 7 and 8.
