Embodiment Construction
[0012] The screening and reverse verification process of the serum markers of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0013] The present invention collects and sorts out 160 liver cancer tissue sample banks, including preoperative peripheral blood, postoperative liver cancer tissue, adjacent normal tissue, and related clinical case data. refer to figure 1 The flow shown is for reverse serum-proteomics experimental research.
[0014] 1. Samples to be collected, each case contains:
[0015] 1) Tumor tissue paraffin block × 1;
[0016] 2) Fresh specimens of tumor tissue x 1 are stored in a -80°C refrigerator;
[0017] 3) Paraffin block of normal liver tissue adjacent to the tumor × 1;
[0018] 4) A fresh specimen of normal liver tissue adjacent to the tumor x 1 is stored in a -80°C refrigerator;
[0019] 5) Store the plasma supernatant × 1 in a -80°C refrigerator after two centrifugations;
[0020] 6) After ce...
