Acridinium ester labeled compound and detection kit

The invention relates to an acridinium ester labeled compound and a detection kit. The acridinium ester labeled compound comprises a body, a labeled group labeled on the body and a modification group connected to the body, the labeled group is an acridinium ester group, and charges carried by the modification group and charges carried by the body are same charges. When the acridinium ester labeled compound is used for immunodetection, the luminescent value of a background is small, the signal-to-noise ratio is high, and false positive does not occur easily. 本发明涉及一种吖啶酯标记复合物和检测试剂盒。该吖啶酯标记复合物包括本体、标记于本体上的标记基团、和连接于本体上的修饰基团，标记基团为吖啶酯类基团，修饰基团所带电荷与本体所带电荷为同性电荷。上述吖啶酯标记复合物用于免疫检测时，本底的发光值较小，信噪比较高，不容易出现假阳性。
