図2A〜2Bは、siRNAリポプレックスのHEK細胞およびHeLa細胞への細胞取り込みにおけるポリアニオン性オリゴ糖の効果をそれぞれ示す。
懸濁注射液(Injection suspension)
所望のタンパク質用の作動コーディング(operative coding)を含む核酸、すなわち細胞取り込みでタンパク質の発現をもたらすことができる核酸(たとえば、RNAやDNA、必要に応じてプラスミドの形態のRNAやDNA)が、滅菌された生理的緩衝水溶液中で、1:5の重量比で錯化剤または遺伝子導入剤(たとえば、Lipofectamine(商標)、SuperFect、またはEDOPCなど)と複合体化され、従来の方式でポリプレックスまたはリポプレックスを形成する。投与前に、重合度DPが10であるグルロン酸ナトリウム(WO2008/125828に記載のように調製)が、錯化剤/遺伝子導入剤に対する重量比1:1で添加される。
懸濁注射液
所望のタンパク質用の作動コーディング(operative coding)を含む核酸、すなわち細胞取り込みでタンパク質の発現をもたらすことができる核酸(たとえば、RNAやDNA、必要に応じてプラスミドの形態のRNAやDNA)が、滅菌された生理的緩衝水溶液中で、核酸塩基単位でのキトサンアミンに対する比が1:10になるよう、キトサンと複合体化される。投与前に、重合度DPが10であるグルロン酸ナトリウム(WO2008/125828に記載のように調製)が、前記キトサンに対する重量比1:5で添加される。
粘液層のある場合の細胞へのマイクロビーズの取り込み
粘液分泌HT29−MTX細胞のマイクロビーズを取り込む能力を評価する。不連続の粘液層を有する細胞と、連続する粘液層を有する細胞とについて下記のように調べた。
siRNAリポプレックスの細胞取り込みに対するポリアニオン性オリゴ糖の効果
HeLa細胞またはHEK細胞(市販)を、optiMEM(商標)成長培地(インビトロジェン社)を使用して6穴プレートでコンフルエントになるまで成長させた。
