Characterization of the MenX–CRM197 conjugates tested in mice

Conjugate Conjugation chemistry avDP MenX OS MenX/CRM197, wt/wt MenX/CRM197, mol/mol Kd Endotoxin, EU/µg
MenXOX–CRM197 Random 80 0.69 1.7 0.07 1.6
MenX–ADH–SIDEA–CRM197 Selective with longer spacer 17 0.36 4.1 0.22 5.3
MenX–NH2–SIDEA–CRM197 Selective 17 0.33 3.7 0.24 0.8

Kd values were of 0.33 for unconjugated CRM197 and of 0.24 and 0.40 for MenX OS of average degree of polymerization (avDP) 80 and 15, respectively.
