Pseudomonas aeruginosa recombinant protein OprL as well as preparation method and application thereof

The invention provides a pseudomonas aeruginosa recombinant protein OprL as well as a preparation method and application thereof. Animal tests show that the recombinant protein can effectively stimulate an organism to generate relatively high humoral immunity response and excellent immune protective effect, so as to facilitate prevention, diagnosis and treatment of pseudomonas aeruginosa. The recombinant protein prepared according to the preparation method is high in expression quantity and convenient to separate and purify.
