ADAMTS13 is inhibited and partially cleared in baboons injected with 3H9. (A) The residual mean ADAMTS13 activity (Ac) and (B) antigen (Ag) levels were measured in citrated plasma from subject (●, n = 6) or control baboons (■, n = 5) relative to baseline (0 hours) and are shown in function of time. Error bars represent SD, and dashed horizontal lines indicate the lower detection limit of the performed assay. Arrows indicate moments of injection.
