Abstract

A DNA fragment encoding the hepatitis B virus surface antigen was amplified from a positive blood (hepatitis B) sample and introduced into the pET 32c prokaryotic expression vector. The gene encoding the HBV surface protein antigen was introduced into pCAMBIA 3300, and immobilized into Agrobacterium tumefaciens strain LBA4404. Cotyledonary leaf sections of Cucumis sativus (cucumber) cv ‘Swarnamukhi’ were cocultivated with Agrobacterium harboring the binary vector pCAMBIA 3300 carrying the HBV surface antigen gene driven by the CaMV35S promoter and the herbicide resistance gene phosphinothricin. Putative transformed shoots were induced on a Murashige and Skoog (MS) medium containing phosphinothricin, and these were then rooted on MS basal medium supplemented with 1 mg/L Indole 3-butyric acid (IBA). Integration of the T-DNA into in putative transgenic plants was confirmed by PCR and Southern blot analyses. RT-PCR and Northern blot analyses were conducted to determine RNA expression. Levels of expression in transgenic plants were confirmed by Western blot analysis, and quantification of the protein was determined by enzyme linked immuno assay (ELISA). Molecular mass of the recombinant protein was measured by Matrix-Assisted Laser Desorption Ionization-Time-of-Flight (MALDI-TOF) Mass Spectrometry.
