BacMam Platform for Vaccine Antigen Delivery.

ABSTRACT

Recombinant baculo viruses based on Autographa californica multiple nuclear polyhedrosis virus carrying vertebrate cell active expression cassettes, so-called BacMam viruses, are increasingly used as gene delivery vectors for vaccination of animals against pathogens. Different approaches for generation of BacMams exist and a variety of transfer vectors to improve target protein expression in vivo have been constructed. Here we describe a use of transfer vector which contains an insect cell-restricted expression cassette for the green fluorescent protein and thus enables easy monitoring of BacMam virus rescue, fast plaque purification of recombinants and their convenient titer determination and which has been proven to be efficacious for gene delivery in vaccination/challenge experiments.
