Detection method and scheme of ICG strip. A: Structure of ICG strip. N-terminal 103 amino acids of N protein and rabbit IgG were placed at the test line and control line, respectively. The ICG strip consisted of 4 membrane pads: sample pad, conjugate pad, nitrocellulose membrane and absorbent pad. Protein A-colloidal gold conjugate was kept in the conjugate pad. B: Detection method. Two μl of serum was diluted with 150 μl of PBS and then placed in a microtiter well. The strip was dipped in the solution. After standing still for 15 min, the test line and/or control line appeared.
