<EPO mRNA内包脂質ナノ粒子の調製>

mRNA内包脂質ナノ粒子の粒子径は、脂質ナノ粒子分散液について、粒径測定装置NanoSAQLA(大塚電子)を用いて、リン酸緩衝生理食塩水(PBS)で5倍希釈し、測定した。結果を表1に示す。
(総mRNA濃度定量)
EPO mRNAをMilliQ水で希釈して100μg/mLから3.1μg/mLまでの2倍希釈系列で希釈サンプルを調製し、検量線溶液を調製した。検量線溶液もしくはmRNA脂質ナノ粒子50μLをメタノール450μLと混合して測定溶液を調製した。
Quant-iT RiboGreen RNA Assay Kit(Thermo Fisher Scientific)を用い、標準添加法により外水相核酸濃度を定量した。まず、上述のキットに含まれる20×TEバッファーを水で希釈し、1×TEバッファーとした。なお、TEは、Tris/EDTA(エチレンジアミン四酢酸)を示す。EPO mRNAを終濃度が0~400ng/mLになるようにTEバッファーで希釈し、核酸希釈系列を調製した。TEバッファーで5倍希釈したmRNA脂質ナノ粒子10μLと核酸希釈系列90μLを96ウェルプレートで混合後、TEバッファーで200倍に希釈したRiboGreen試薬100μLを各ウェルに加え,蛍光プレートリーダー(Infitite 200 Pro M nano +、TECAN)を用いて蛍光 (励起波長:485nm,蛍光波長:535nm) を測定した。得られた結果から標準添加法に則り、各測定溶液の外水相核酸濃度を算出した。
上述の工程で得られた総mRNA濃度および外水相でのmRNA濃度の定量結果を用いて、下記式に従って、mRNA脂質ナノ粒子のmRNA内包率を算出した。結果を表1に示す。
mRNA内包率(%)=(総mRNA濃度-外水相におけるmRNA濃度)÷総mRNA濃度×100
ICRマウスに上記<EPO mRNA内包脂質ナノ粒子の調製>において調製したmRNA脂質ナノ粒子の分散液をmRNA投与量として0.1mg/kgになるように静脈内投与した。投与6時間後に後大静脈より採血を行い、血漿を得た。得られた血漿を用いてErythropoietin (EPO) Human Elisa Kit(Abcam)を使用してヒトEPO酵素活性を定量した。定量値は比較例1を1としたときの相対的EPOタンパク量で記載した。
結果を表2に示す。
