ProCode

ProCode Intrabody Selection Overview:

Next-generation scFv platform in bacteria: Novel quality control selection eliminates scFv aggregation in bacterial systems.

Key advantages

  • Proprietary libraries (filter out stops, control expression levels and eliminate aggregation)
  • ProCode scFvs are engineered as vectorized Intrabodies (AAV delivery)
    • Validated for intracellular targets
    • Intrabody based drugs cut across all therapeutic areas
  • Only direct Intrabody platform
  • Compatible vectors for multiple formats: scFv, bivalent and bispecific miniMab formats (scFvs to IgG cassettes)
