As a virus, an influenza virus (Influenza virus type A H1N1) was prepared. Put 3 mL of the virus solution added to the maintenance medium (1% FBS-added culture medium) in a sterilized bag, and immerse each specimen with the above coating film in it for 24 hours (37 ° C, 5% CO 2 conditions Bottom), incubated, and after 24 hours, the virus solution was taken out. Viral activity was determined by quantitative RT-PCR.
定量ＲＴ－ＰＣＲ法の具体的な手順としては以下のように行った。各検体から取り出したウイルス液をTrizol試薬(ambion)を用いてTotal RNAの抽出を行った。抽出したRNAからPrimeScript RT Master Mix (Takara)の方法に準じてcDNAに逆転写し、SYBR Premix EX Taq II (Takara)により増幅を行った。なお、５０μＬ（25μＬ SYBR Green Mix (2x), １μＬ cDNA, ２μＬ primer pair mix (５ｐｍｏｌ／μＬ each primer), ２２μＬ Ｈ２Ｏ）のＰＣＲ反応液を用い、反応は９５℃にて３０秒を１サイクル、さらに９５℃にて５秒および６０℃にて３０秒のサイクルを５５サイクルの条件にて行った。結果はΔCt法により求めた。即ち、検体１（コントロール）に対する各検体のサイクル数の差に－１を乗じたΔCt値を求め結果とした。また、検体１（コントロール）に対する相対比（倍数）を、２ΔCtにより求めることができる。なお、検出されない検体については、５５サイクルとして算出した。ΔCt値及び相対比が小さいほど、抗ウイルス効果が高いことを示す。
A specific procedure of the quantitative RT-PCR method was performed as follows. Total RNA was extracted from the virus solution taken from each sample using Trizol reagent (ambion). The extracted RNA was reverse transcribed into cDNA according to the PrimeScript RT Master Mix (Takara) method, and amplified with SYBR Premix EX Taq II (Takara). A PCR reaction solution of 50 μL (25 μL SYBR Green Mix (2x), 1 μL cDNA, 2 μL primer pair mix (5 pmol/μL each primer), 22 μL H 2 O) was used, and the reaction was carried out at 95° C. for 30 seconds for one cycle. Furthermore, 55 cycles of 95° C. for 5 seconds and 60° C. for 30 seconds were performed. The results were obtained by the ΔCt method. That is, the ΔCt value obtained by multiplying the difference in the number of cycles of each specimen with respect to the specimen 1 (control) by -1 was obtained as the result. Also, the relative ratio (fold) to sample 1 (control) can be determined by 2 ΔCt . For undetected specimens, the number was calculated as 55 cycles. A smaller ΔCt value and relative ratio indicates a higher antiviral effect.
