Figure 5. Inhibitor titers to FVIII ortholog in pre-immunized murine hemophilia A plasmas.
Mice were immunized with either rhFVIII (A) or rpFVIII (B), respectively. Following the 7th injection, plasma was collected via terminal cardiac puncture and assayed for inhibitor titer to the original immunogen and roFVIII via modified Bethesda assay. Lines connect the intramouse inhibitor titers recorded for the two FVIII orthologs. N = 6 and 10 respectively.
