...etting insert-containing tomatoes against HSV-2gD. Specific expression of the introduced antigen construct at the RNA level was detected by RT-PCR, using specific primers for the HSV-gD2 transcript. Expression of the HSV-2 gD antigen was assayed by ELISA on protein extracts isolated from same transfected plant tissue samples as for the RT-PCR assays. Results showed that the HSV-gD2 construct was expressed at both the RNA and protein levels in the transgenic to...
