Recombinant Protein Expression

We at Bon Opus Biosciences proudly offer industry-trusted and affordable recombinant protein expression services. Our distinct services offer the time and space to collaborate, fulfill, and exceed client requests in a reliable delivery window of 8 to 10 weeks. Our team of experienced and trusted scientists and researchers work diligently in ensuring each request receives the respect it deserves, offering our clients an affordable expression service with transparency, efficiency, and affordability. We carefully crafted our unique workflow to optimize insect expression with virus preparation to ensure accuracy and timely delivery. For custom protein expressions with insect cells, Bon Opus is your premier solution.  

 

Insect Recombinant Protein Expression Workflow 

 

Our general workflow follows a transparent step-by-step process, ensuring you’re comfortable with production and aware of potential challenges or favorable outcomes. We start by taking the constructed donor plasmid and transforming this into E. coli. E. coli is an integral part of protein expression services and requests. The E. coli to extract recombinant bacmid to begin transfecting insect cells. The additional step of virus preparation and generation contributes to the 8-to-10-week delivery window, but it is a vital step in the general workflow.  

​

From virus generation, we complete a virus expression process and enter purification and scaling. Upon completion of our insect protein expression system, we verify and review all details and pertinent data as it relates to your request. From there, we prepare your order for delivery. Our innovative and collaborative workflow sets the bar high for all available protein expressions, and we curated a system designed to fulfill our clients’ requests. 
 
We value the need for reliable recombinant protein expression services, and we work hard to keep our services affordable and accurate. Regardless of your request and origin, we can partner with you to define and deliver the needed insect or other host cell custom protein requests. We work with E. coli, yeast, mammalian, bacterial, and insect hosts, offering a wide range of custom services and solutions.
