rAd transduction efficiencies for pig cells. (A) The schematic structure of Ad vector for amiRNA expression. ITR, inverted terminal repeat of adenovirus; PCMV, immediate early promoter of cytomegalovirus; miR, miR-flanking sequences of mouse BIC non-coding mRNA; Pre-amiRNA, double–stranded oligonucleotide for amiRNA; IRES, internal ribosome entry sequence; GFP, green fluorescent protein coding sequence; SV40 pA, poly(A) signal of SV40 virus. (B) PK-15 cells and (C) primary PAMs were transduced with different doses of rAd-amiRSn and the GFP-positive cell numbers were measured by flow cytometry 48 h after transduction. (D) Primary PAMs and PK-15 cells were mock-transduced or transduced with each rAd and analyzed by fluorescent microscopy (40×) 48 h after transduction.
