Anti-IL-4 Conjugate Vaccine Prepared with PeliCRM197 is More Immunogenic than KLH Analog

Comparable Immunogenicity Observed in Peptides Coupled to PeliCRM197 and KLH in a Murine Model
In this case study, 3 peptides (peptides #5, #6, and #7) directed to one therapeutic target were conjugated to either CRM197 (a non-toxic diphtheria toxin mutant) produced with Pfenex Expression Technology® or to KLH (keyhole limpet hemocyanin).
