Epitope Discovery Service & Seromarker Profiling

Our epitope dicovery service offers incubation and data evaluation on the basis of our peptide array technology PepStar™.  By using JPT's high content peptide microarrays, proteome-wide profiling of immune responses and epitope discovery becomes reality for the first time. Our peptide array services range:

  • Efficient profiling of B-cell epitopes
  • Serological screening for novel peptide binders and biomarkers
  • Epitope mapping
  • Profiling and screening of antibody preparations and patient samples
  • Detection of immunodominant regions in single antigens
  • Studying infectious and autoimmune diseases, allergies and cancer
  • Applying whole proteome libraries or random peptide displaying microarrays

Applications for Epitope Discovery Service & Seromarker Profiling

  • Identification of seromarkers for cancer, infectious & autoimmune diseases and allergies
  • Peptide biomarker validation
  • Multiplexed immune monitoring in clinical trials
  • Elucidation of antibody signatures in vaccination studies
  • Monitoring of humoral immune responses
  • Identification of novel vaccine targets

"Carolus’ technology enabled the development of therapeutic peptides and antibodies that target specific interactions between macrophage migration inhibiting factor and its chemokine receptors as well as RANTES and platelet factor-4. JPT's PepStar™ peptide microarray platform as well as its full profiling service and data interpretation capabilities have been a reliable and robust approach to elucidate the molecular details of these protein- protein interactions."
Dr. Joshua Schultz (Carolus Therapeutics, Inc., San Diego, CA, USA)
