IHC (immunohistochemistry) kit for human-derived CD13 soluble protein as well as application of IHC kit

The invention relates to an IHC (immunohistochemistry) kit for human-derived CD13 soluble protein as well as an application of the IHC kit. The IHC kit can be applied to detection of HCC (hepatocellular carcinoma) cell CD13 antigens of humans, and the expression quantity of CD13 is used as a recurrence detection index of HCC patients after recovery. The IHC kit has the advantages as follows: the IHC kit takes tumor tissue of the patients as detection samples, and the IHC kit has the characteristics of rapidness, good sensitivity, high specificity, easiness in popularization and application and the like; the IHC kit can be used for guiding adjuvant therapy after HCC operations, and the postoperative recurrence rate of high-risk patients is decreased.
