Resumen:
Abstract The dengue virus envelope glycoprotein (DVE) has been identified as a promising candidate for the development of a subunit vaccine and to provide an antigen for diagnostic kits. In this study, cell suspension cultures of has been identified as a promising candidate for the development of a subunit vaccine and to provide an antigen for diagnostic kits.

In this study, cell suspension cultures of The dengue virus envelope glycoprotein (DVE) has been identified as a promising candidate for the development of a subunit vaccine and to provide an antigen for diagnostic kits. In this study, cell suspension cultures of Nicotiana tabacum and Morinda citrifolia were transformed and evaluated for production of the DV-E serotype 2 protein. The expression cassette consisted of the DV-E gene along with a signal peptide at its 50 end. In addition, a KDEL endoplasmic retention sequence was included in a second construct to evaluate its influence on accumulation levels of the recombinant protein. Expression cassettes were sub-cloned into a binary vector pCAMBIA 1305.2, and transformation was carried out using Agrobacterium tumefaciens. Transformed cell lines of both N. tabacum tumefaciens.
