Fig. 6From: Identification of the largest non-essential regions of the C-terminal portion in 3A protein of foot-and-mouth disease virus for replication in cell cultureSequencing chromatogram of the supernatants from transfected cells. The cell culture supernatants from transfected cells were harvested and RNAs were extracted with viral RNA mini kit. The cDNA fragments containing 3A were amplified by RT-PCR and sequenced an ABI 3700 sequencerBack to article page
