Technology Platforms for Novel Recombinant Conformational Proteins

Conigen Soluble Proteins (CSP™) & Conigen Membrane Proteins (CMP™)

  • No need for developing corresponding cell line for every target
  • CSP can preserve the native conformations similar to those on cell surfaces
  • Easy to scale-up and develop high-through-put assays
  • No host cell proteins
  • Dramatically higher number of molecules for each immunization
  • Highly immunogenic
  • Preserves the native conformations similar to those on cell surfaces
  • CSP not limited to monomeric proteins without critical conformational epitopes on the quaternary structures
  • Provides better conformational epitopes for antibody screening and affinity evaluation
  • Enhances assay sensitivity and potency; generates wider windows for agonist and antagonist activity evaluation
  • Better conformation for antibody/antigen, receptor/ligand complex structural analysis
  • More natively folded proteins in the cellular membrane bilayer without further processing
  • Eliciting antibodies that better target conformational epitopes
  • Higher antigen dosage per immunization
  • Reduced number of host cell derived proteins
  • More immunogenic
