Supplementary Figure 1. Efficiency of DNA, RNA, and total nucleic acid (TNA) extraction kits in isolating DNA and/or RNA from serially diluted DNA viruses [bovine herpesvirus type 1 (BHV-1) and porcine circovirus type 2 (PCV-2)] and RNA viruses [porcine epidemic diarrhea virus (PEDV) and porcine rotavirus type A (PoRVA)] as measured by conventional polymerase chain reaction (PCR), nested (n) PCR, reverse transcription (RT)-PCR, and/or RT-nPCR assays. The expected molecular size of the correct PCR product from BHV-1, PEDV, PCV-2, and PoRVA is 235, 251, 966, and 121 bp, respectively. PC and NC stand for positive control and negative control, respectively. The thick line on the top of each digitalized gel picture indicates serial dilutions of each virus produced the positive result by the given extract kit and the given PCR.
