flashBACULTRA™ is an improvement over both the flashBAC™ and flashBACGOLD™ systems due to the removal of three more virus genes (p10, p74 and p26) from the flashBACULTRA™ genome.

Advantages:

• Increased recombinant protein transcription from the polh promoter
• More efficient transport through the endoplasmic reticulum (ER) and secretory pathway
• Increased cellular stability and longevity
• Increased recombinant protein secretion
• Increased recombinant protein yield
• Reduced proteolysis and degradation
• Increased recombinant protein quality

Baculovirus DNA	chiA deleted	v-cath deleted	P10/P26/P74 deleted	Applications
flashBAC™				• Expression of secreted and membrane targeted proteins
flashBACGOLD™				• Reduced proteolysis • Improved secretion and membrane targeting
flashBACULTRA™				• Increased transcription of polh promoter giving higher yields • Increased protein quality due to improved cellular stability • Reduced proteolysis • Improved secretion and membrane targeting

For a listing of recent publications which have used the flashBAC expression system, please see our listing of flashBAC publications.

flashBACULTRA™ is also included as an integral part of the new Baculovirus Expression System, baculoCOMPLETE™.
