Fig. 5From: Intracellular delivery of messenger RNA by recombinant PP7 virus-like particles carrying low molecular weight protamineCytotoxicity and thermal stability of 2PP7-Protamine and 2PP7-Protamine-GFP VLPs. 2PP7-Protamine and 2PP7-Protamine-GFP VLPs show low cytotoxicity in Cos-7 cells (a-c) and high thermal stability at different temperatures (d). The cytotoxicity has been expressed in terms of cell viabilityBack to article page
