Thus our expression system can be used in insect cell lines under minimal biosafety conditions. The baculovirus polyhedrin or p10 is normally highly expressed during the late stages of infection and is not essential for the pathogenesis and replication within a host insect cell. Depending on the design of the study, baculovirus vectors allow for sustained gene expression or are able to induce an immune response directed against the delivered and/or displayed gene product. The insect cell-based BEVS has been extensively used to produce many diverse types of recombinant proteins for research, medical, agricultural, and veterinary purposes. Maybe you should try expression in an insect cell! The Baculovirus Expression Vector System satile eukaryotic expression systems available. For thirty years researchers have been using this platform to express recombinant proteins, and thousands of proteins have been successfully expressed and purified. The insect based Baculovirus Expression Vector System (BEVS) has shown its utility in large-scale production of both proteins and viral vectors. This is very useful in regards to virology studies and biotechnology applications. After the very first transfection of the bacmid, you will produce high titers of pure recombinant baculovirus particles, saving weeks of precious time and enabling large-scale protein expression experiments. The most widely used baculovirus species for basic virology and biotechnology is Autographa californica multiple nucleopolyhedrovirus (AcMNPV). Spodoptera frugiperda (Sf9) insect cells are cotransfected with the transfer vector (donor or shuttle) plasmid DNA containing the foreign gene to be expressed and BaculoGold™ DNA (PharMingen), Bac-N-Blue™ DNA (Invitrogen), or BacPAK6™ DNA (Clontech).

A baculovirus is an enveloped double-stranded DNA virus that belongs to the Baculoviridae family, which affects approximately 600 different insect species. This is due to the structural changes within a host following a viral infection (referred to as the cytopathogenic effect). The baculovirus polyhedrin or p10 can be replaced with a gene of interest, which allows for the promoters to expresses the gene in abundance allowing for a very high concentration of the gene of interest to be made. The helper plasmid expresses the Tn7 transposase. 26 December 2020. The BEVS contains several bottlenecks that hinder the efficiency and use of it. To target hepatocytes, the Rous sarcoma virus (RSV) promoter is used to mediate the expression of the lacZ gene. The corresponding VL gene fragment should be introduced by using the recognition sites of the enzymes SacI and HindIII. The expression time limit is 22-24 hours after infection.
