Patent ID: 11959912

Abstract:
A fluorescence immunochromatographic detection card and a preparation method therefor and usage thereof is disclosed. The fluorescence immunochromatographic detection card comprises a treatment liquid A, a treatment liquid B, and a detection card. The treatment liquid A contains an antibody 15C4 that is coupled with a fluorescent microsphere. The treatment liquid B contains an antibody 13G12 that is coupled with biotin. The detection card comprises a detection line area and a quality control line area, and a streptavidin detection T line is fixed in the detection area, and an antibody quality control C line is immobilized in the quality control line area. The preparation method comprises: (1) formulating the treatment liquid A; (2) formulating the treatment liquid B; and (3) drawing the line on the detection card. The fluorescence immunochromatographic detection card has characteristics such as high sensitivity, high specificity, and high stability, and can be applied to the rapid detection of disease markers.
