Key Problem and Market Opportunity

  • Using site-directed mutagenesis for protein engineering to make better enzymes, antibodies, and protein drugs lacks throughput and scalability
  • Protein function not only depends on one or two amino acids but a combination of changes in many cases

Key Advantages of the Technology

Technology Section Slider 1
Technology Section Slider 2
  • Simultaneously study the interaction of different amino acids in a protein at a much faster speed
  • First platform for assembling and barcoding protein-encoding sequences carrying multiple mutations en masse
  • Coupled with next-generation sequencing to track all variants in an unprecedented throughput
  • Uses barcoded sequences to easily identify the functional variants
  • Helped to identify a better error-free Cas9 protein
