Heterophilic antibody blocking agent and myoglobin detection kit

The invention provides a heterotropism antibody blocking agent. The heterotropism antibody blocking agent comprises a light chain and a heavy chain, the amino acid sequence of the light chain is as shown in SEQ ID NO.1, and the amino acid sequence of the heavy chain is as shown in SEQ ID NO.2. The invention also provides an application of the heterotropism antibody blocking agent in preparation of a myoglobin detection kit and the corresponding kit. The heterotropism antibody blocking agent is a self-researched product specially designed for myoglobin detection, and can effectively remove interfering substances in serum; by adopting the heterotropism antibody blocking agent, the reagent performance can be greatly improved, the false positive rate is reduced, and a reliable guarantee is provided for a detection result. 本发明提供了一种异嗜性抗体阻断剂，包括轻链和重链；所述轻链的氨基酸序列如SEQ ID NO.1所示，重链氨基酸序列如SEQ ID NO.2所示。本发明还提供了一种上述异嗜性抗体阻断剂在制备肌红蛋白检测试剂盒中的应用以及对应的试剂盒。本发明异嗜性抗体阻断剂是专门针对肌红蛋白检测设计的自研产品，可有效去除血清中的干扰物质；采用该异嗜性抗体阻断剂，能够大大提高试剂性能，减少假阳率，为检测结果
