Recombinant Protein Expression in Yeast Cells
Similar to mammalian cells, yeast cells confer eukaryotic processing, folding, and post-translational modification. At the same time, a yeast expression system delivers high level expression. Bon Opus has established an efficient system for yeast cell recombinant protein expression, which includes the design of signal sequences, expression vectors, and a set of yeast strains (X33, GS115, KM71, and SMD1168). Our team incorporates the use of antibiotic gradients to screen for transformants with the highest numbers of inserts, and thus ensure a high expression level in the follow-up production phase.

The Purpose for Yeast Expression
Yeast is an excellent host cell strain for recombinant eukaryotic expression demands because it’s fairly easy to manipulate during the workflow. Specific proteins are expressible with yeast because of this easy manipulation, and both heterologous and endogenous are included. With an easy workflow system, Bon Opus Biosciences can produce highly robust and production yeast host cell strain yields for a wide range of applications, including biopharmaceutical and industrial demands. Our yeast protein production workflow is distinct, with a hands-on approach for each application.
Bon Opus Biosciences Distinct Workflow Design
Our team of in-house lab and quality control experts work diligently to complete a thorough six-step process. In each step, we take you along with us to ensure your satisfaction and resolution should any issues arise. To begin our custom recombinant protein production in yeast cells, we spend two weeks synthesizing the cells, undergoing codon optimization, and preparing the DNA. We house a distinct inventory of preclinical DNA prep that can work for your application. After thorough completion of the synthesizing, we spend one week transforming the genes to P. pastoris cells. This allows us to spend time screening the production for copies. From here, we spend two weeks expressing, evaluating, and optimizing. Optimization is imperative in most custom services because it allows us to use fusion tags that offer custom and robust yields. We will take the fully optimized protein and scale-up with purification as it suits the protein of interest. At the end of all yeast protein production services, we complete our in-house quality control and prepare the yields for on-time delivery.
