Therefore conclude that degree of quaternization of chitosan increased so did not result in more efficient gene delivery. There are also more cell toxicity.
Therefore, it is concluded that the degree of quaternization of chitosan, the more it did not affect performance in the delivery of genes. They are toxic to cells even more.
It can be concluded that the degree of quaternization of chitosan more that did not have the increase in การนำส่ง gene There is also a cytotoxicity even more
