Moreover, red fluorescence could be obviously visualized in the tumor cells after RGP delivery, which was attributed to the intrinsic characteristics of genipin.Conclusion: The protein–polymer hybrid system prepared via the genipin-mediated crosslinking has exhibited potential to be used as a theranostic platform for both in vivo imaging and delivering diverse therapeutic proteins.Keywords: genipin, polyethyleneimine, ribonuclease A, protein delivery, antitumor efficacy |
