S were transfected with pshRNA-UBE2D3 and negative control. Samples were collected at the indicated time points and fixed in 70 ethanol overnight. For cell cycle analysis, fixed cells 10781694 were treated with RNase for 20 min before addition of 5 mg/mL PI and analyzed by FACS. Meanwhile, cells dilutedFigure 1. The total RNA, isolated from Human MedChemExpress Nobiletin laryngeal squamous cell carcinoma radioresistant cell Hep2R, was used to synthesized the first-strand cDNA and double-strand cDNA by SMART method (Clontech). The cDNA fragments were inserted into the pGADT7 vector, and the recombinant phage were packaged in vitro. A small portion packaged phage was used to infected DH10B Competent Cells. Titration and the positive clones were assayed by PCR. Fig. 1 shows the inserted fragment of Hep2R cell full length cDNA library detected through construction electrophoresis.
