CRISPR-based multiplexed genome editing for improved heterologous protein engineering and expression in E. coli

During this webinar, discover how Inscripta experts generated an Escherichia coli saturation mutagenesis library against an integrated green fluorescent protein (GFP) using CRISPR-based technology, in a few short weeks. Several engineered variants showed distinct intensity and spectral characteristics, including several literature-validated spectral variants as well as novel variants. Also uncover how a library of all predicted E. coli promoters and ribosome binding sites (RBS) 5′ of the integrated GFP start codon was generated, capable of identifying bins of low, medium and high strength under minimal and rich media.
Learn how these high-throughput profiling experiments provide excellent insights into genetic regulation and successfully deliver a measure of native sequences. The applications presented in this webinar demonstrate the power of the Onyx platform to improve heterologous-protein engineering and expression workflows while generating new biochemical insights.

What will you learn?

  • How to develop and analyze site saturation mutagenesis libraries for heterologous-enzyme engineering to improve activity
  • How to improve expression of heterologous proteins in E. coli using genome-wide editing libraries
