Our aim was to construct immunoconjugates (ICs) bispecific for epidermal growth factor receptors (EGFRs) and the intranuclear cyclin-dependent kinase inhibitor (CDKI) p27(Kip1) modified with nuclear-localizing sequences (NLSs) to facilitate their nuclear uptake following EGFR-mediated internalization."
