A dicistronic construct allows easy detection of human CFTR
... We have made a dicistronic construct where the picornaviral internal ribosome-entry site (IRES) driving the expression of the β-geo gene has been inserted into the 3′ untranslated region of the human CFTR gene present in a YAC. When introduced into the human cell line Caco-2 expressing the CFTR gene ...
