    • Use of labeled monoclonal antibody 50 H.19 to detect the location and concentration of blood platelets in a host is disclosed. MAb 50 H.19 labeled with a label which can be detected from without the host (e.g. a radiolabel or NMR-label) is intravenously injected to immunoreact with platelets in vivo or is first immunoreacted in vitro with platelets, which are then intravenously injected into the host. By means of the labeled MAb 50 H.19 bound platelets it is possible to detect and locate thrombi, emboli, atherosclerotic obstructions, bacterial endocarditis and to do spleen imaging. In another embodiment of the invention, the MAb 50 H.19 is bound to an enzymatic thrombolytic agent and injected intravenously to permit the therapeutic application of the agent directly to thrombi.
    • 公开了使用标记的单克隆抗体50H.19来检测宿主血小板的位置和浓度。 静脉内注射可从体内检测无标记物(如放射性标记或核磁共振标记)的标记的MAb 50 H.19,与血小板体内免疫反应或首先在血小板上进行体外免疫反应,然后静脉注射 主人。 通过标记的MAb 50 H.19结合血小板,可以检测和定位血栓,栓塞,动脉粥样硬化障碍,细菌性心内膜炎,并做脾脏成像。 在本发明的另一个实施方案中,MAb 50H.19与酶溶血栓剂结合并静脉内注射以允许药物直接治疗性施用于血栓。
