If starting from a protein sample (for instance, affinity purified antibodies from a patients blood), scientists can use mass spectrometry to determine the amino acid sequences of the antibodies and then synthesize the genes that encode those amino acids (Tran et al., 2016). Immunization against different strains, need to fewer amount of vaccine, multivalent vaccines and inducing long-lasting immune responses could be considered as potential advantages of DNA vaccines which can be referred. Trevors J.T., Barkay T., Bourquin A.W. Then they remove a loop of bacterial DNA . Aiba S., Koizumi J. Generally speaking, expression of a foreign gene requires restructuring the gene to include sequences that are required for producing an mRNA molecule that can be used by the host's translational apparatus (e.g. The recombinant plasmid encoding EG95 antigen was successfully constructed and identified by PCR, restriction enzyme digestion and sequencing. [12] Recombinant DNA is used to identify, map and sequence genes, and to determine their function. (1988) Probe-directed polymerization-enhanced detection of specific gene sequences in the environment. Tomasz A. If the rDNA sequences encode a gene that is expressed, then the presence of RNA and/or protein products of the recombinant gene can be detected, typically using RT-PCR or western hybridization methods.

Recombinant DNA is a technology scientists developed that made it possible to insert a human gene into the genetic material of a common bacterium. Recombinant protein expression in bacteria requires the insertion of a DNA fragment ( open reading frame, ORF) into an expression vector, routinely a plasmid vector and the transferral of this vector into bacterial cells ( transformation ). The gene can be cloned into recombinant plasmids that are over-expression vectors. Vaccination trials in Australia and Argentina confirm the effectiveness of the EG95 hydatid vaccine in sheep.
