Insect Cell Expression

The baculovirus expression system is specially designed to eliminate the need to separate the recombinant virus from the parent virus by plaque purification or any other means. The production of recombinant viruses has been reduced to one step in insect cells, so it is fully suitable for high-throughput and automated production systems. The system uses an AcMNPV genome lacking essential genes (ORF 1629), which contains a bacterial artificial chromosome (BAC) at the polyhedral gene locus, thereby replacing the polyhedral coding region. Basic gene deletion can prevent viruses from replicating in insect cells, but BAC allows viral DNA to be maintained and reproduced as circular genomes in bacterial cells.

Advantages of insect cell expression systems

  • Simple to use
  • One step production of recombinant virus in insect cells
  • No steps needed to purify recombinant virus
  • Amenable to high throughput and automated systems
  • Maximises production of secreted and membrane-targeted proteins
  • Back-compatible with a huge range of transfer vectors.

Overall solution

  • Insect Scale-up Expression
  • Cloning into expression plasmid, and P1 virus generation
  • 30 ml small-scale expression analysis with affinity pulldown
  • 1 liter expression, and one-step affinity purification
  • Baculovirus Infected Insect Cell Stock Creation (BIIC)
  • Small scale expression scouting and optimization
  • Baculovirus particle (BVP) production for polyspecificity screening


  • The production scale can then be expanded to 10 liters or higher to produce the protein quality required by customers.
  • Available options: low endotoxin treatment, affinity tag removal by protease cleavage, protein titration and quantification (HPLC), analytical protein characterization, including SEC-HPLC, C-IEF, thermal stability analysis, mass spectrometry, and protein formulation optimization.
