Methods S-180 tumor imaging and autoradiography of angiogenesis on Matrigel model was developed with 99 Tcm-recombinant human angiostatin ( 99 Tcm-rhAS) as a tracer, and FCM on human microvascular endothelial cell-1 ( HMEC-1) with FITC-rhAS or rhAS antibody. 方法以99Tcm-重组人血管抑素、FITC-重组人血管抑素和FITC-重组人血管抑素抗体为示踪分子,进行小鼠S180肿瘤模型显像、Matrigel血管模型放射自显影和HMEC-1细胞的流式细胞术。
