Best Practices: Perform Small-Scale Expression Optimization

Proteos is an industry leader in the production of high-quality recombinant proteins for drug discovery research.  There are many variables to consider when producing novel recombinant proteins.  Here we will focus on the importance of performing small-scale expression optimization.

Small-Scale Pilot Experiments

Small-scale pilot experiments are the best way to determine the ideal expression conditions for a recombinant protein.

Comparing Systems

Bacterial Expression

For bacterial expression, screening different cell strains, growth mediums, and induction parameters, including temperature, duration, and inducer concentration can improve protein expression in E. coli.

Baculovirus-Infected Insect Cell Expression

For recombinant protein production in baculovirus-infected insect cells, small-scale expression optimizations can identify the best cell line, multiplicity of infection (MOI) and harvest time post-infection.

Mammalian Cell Expression

Similarly, pilot experiments conducted in mammalian cells can identify the ideal cell line, growth temperature, and harvest time based on cell viability.

Conclusions

No matter which expression system being employed, taking the time to optimize conditions during pilot production can drastically improve results during large-scale production.

This will conclude our informational blog series regarding best practices for novel recombinant protein production.
