WebFor each circRNA, two sets of primers were designed: (1) divergent primers to amplify across the backsplice junction, and (2) convergent primers to amplify a linear region within the circRNA. As exons appear in gDNA in a linear fashion, divergent primers should not amplify with this template (Figure S2A; Table S2). WebJun 30, 2024 · Here we focus on circRNAs in the context of Kaposi sarcoma herpesvirus (KSHV) and Epstein–Barr virus (EBV).
