αTAT and mTAT ELISAs. (A) Human αTAT (●) and mTAT (■) captured with an anti–human thrombin mAb and probed with a biotin-labeled anti–human AT polyclonal Ab. (B) Human αTAT (●) and mTAT (■) captured with an anti–human prothrombin fragment 2 mAb and probed with a biotin-labeled anti–human AT polyclonal Ab. (C) αTAT ELISA analyses of WB blood time courses from 4 subjects at 5pM (●) relipidated rTf. Data are shown as the means ± SEM (n = 4).
