The results of animals showed that the labeled antibodies can be cleared fromblood fast, eliminated mainly by kidney, and concentrated significantly in tumor. The tumor can be visualized at 5h after injection and become clear at 9h up to 48h.

• 动物实验结果表明，标记物血液清除快，主要通过肾脏排泄，肿瘤有特异性浓聚，注射后5h肿瘤就开始显影，9h能清晰显影一直持续到48h。
