Fig. 5From: Generation and immunogenicity analysis of recombinant classical swine fever virus glycoprotein E2 and Erns expressed in baculovirus expression systemAgarose gel electrophoresis of samples detected by RT-nestPCR assay. The spleens of the rabbits were collected and total RNA was extracted. The viral RNA was detected by the RT-nestPCR amplification. Lane M: DL 100 plus DNA Marker.
