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 are the best way to determine the ideal expression conditions for a recombinant protein. 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.

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