Vanjske bjelančevine membrane (engl. Outer membrane proteins, Omps) salmonele dokazale su svoju sposobnost kandidata za razvoj cjepiva koje bi se koristilo u prevenciji salmoneloze. S tim je ciljem u ovom radu, pod uvjetima IPTG indukcijskog sustava, provedeno umnažanje i kloniranje te provjerena izražajnost gena za Omp28 iz Salmonelle Typhimurium. Tako dobivena rekombinantna bjelančevina pročišćena je i testirana s obzirom na antigenu sposobnost.
Antigena sposobnost pročišćene bjelančevine potvrđena je uporabom Western blot metode s antiserumom protiv Omps-a iz S. Typhimurium dobivenim od zeca. Genom Omp28 umnožen je kao 330bp produkt. Bjelančevina je imala približno 28 kDa i Western blot analizom pokazala je izraženost jakog signala.
Ovim je istraživanjem zaključeno da Omp28 može poslužiti kao učinkoviti kandidat za razvoj r-DNA cjepiva protiv salmoneloze.
