comparative evaluation and optimization of off-the-shelf

as expected, we found that the m w of cationic polymers does play a major role in affecting their activities. 14 for each class of polymer we thus determined the most effective m w and n/p in transfection, namely the highest transfection efficiency and acceptable cytotoxicity, that were 25 kda at n/p 40 for lpei (fig. 2a), 50–100 kda at n/p

a novel method for dna delivery into bacteria using cationic

in order to verify the influence of the amount of each polymer on the bacteria transformation efficiency, desired aliquots (0.25, 0.5, 1.0, and 5.0 µl) of polymers taken from a 1 mg/ml stock in thf were transferred to plastic microtubes, followed by evaporation of the thf under argon until the formation of a film.

bioreducible cationic polymer-based nanoparticles for low cost,for all polymers, polymerization was completed using a base monomer to side chain ratio of 1.01:1 at 500 mg/ml in dimethyl sulfoxide (dmso) at 90 °c for 24 h while stirring. the polymers were end-capped in dmso at 100 mg/ml with 0.2 m e7 for 1 h at room temperature while shaking.
