Heterologous Protein Engineering and characterization of native regulatory elements in E. coli using Massively Parallel CRISPR Editing

Heterologous protein expression in model organisms has many applications, including protein engineering, production of industrial enzymes and therapeutics, and structure-function discovery. Heterologous proteins are commonly expressed from plasmids to facilitate cloning and genetic manipulation. However, plasmid-based expression has many drawbacks, such as reduced stability and limited control over gene copy number. With CRISPR editing, chromosomal gene integration and subsequent editing has become more accessible, enabling thorough examination of protein expression and function. In this webinar, we demonstrate how we generated an
