Figure 1From: A novel method of modifying immune responses by vaccination with lipiodol-siRNA mixturesLipiodol can serve as a transfection reagent. Day 7 bone marrow derived DC were cultured alone, or with IL-12 p35 specific siRNA delivered by optimized GenePorter concentration (3 μl/culture) or 3 concentrations of lipiodol (1,2, or 3 μl/culture). Following a 24 hour incubation cells were plated at 1 × 106 in 6 well culture dishes and activated for 24 hours with 10 ng/ml LPS and 10 ng/ml TNF-α. Supernatant was harvested and analyzed by ELISA for IL-12 p70 production.Back to article page
