Fig. 5From: Systemic p53 Gene Therapy of Cancer with Immunolipoplexes Targeted by Anti-Transferrin Receptor scFvOptimization of protein/lipid ratios for TfRscFv-LipA2. Different amounts of TfRscFv were incorporated to cationic liposomes by the direct anchoring method, with final proteinllipids ratios of 16–22 µg/µmol. Human breast cancer cells MDA-MB-435 (a) and head and neck cancer cells JSQ-3 (b) were transfected as described in Methods.Back to article page
