Article Title: In Silico Design and Characterization of a Multiepitope Vaccine Candidate Against Brucella canis Using a Reverse Vaccinology Approach

doi: 10.1155/jimr/6348238

Figure Lengend Snippet: (A) In silico cloning of the vaccine construct sequence into the pET-28a (+) expression vector. The construct sequence (blue) was cloned between the vector's EcoRI and BamHI restriction sites (black). (B) 1% agarose gel electrophoresis simulation. The lanes show the molecular weight (MW), and the cloning results in positions 1–3, where lane 1, lane 2, and lane 3 represent the vaccine construct (888bp), the pET-28a (+) (5369bp), and the recombinant plasmid (6245bp), respectively.

Article Snippet: The pET-28a (+) expression vector, obtained from the Addgene database ( https://www.addgene.org/ ) [ ], was selected as the cloning vector.
