Fifteen overlapping segments were amplified from the pDAFL plasmid containing the TMEV genome using high-fidelity polymerase chain reaction. Segments were then digested with the specified restriction enzyme as defined by primer sequences and inserted into the pcDNA 3.1 His A vector to accommodate transfection into the Cos-7 cell line. The TMEV sequences overlap by 30 base pairs to ensure that all potential CD8+ T-cell epitopes are processed for antigen presentation.
Note that the L segment encodes a protein from an alternative reading frame important to TMEV infection.
