Example Embodiment

[0043] Hereinafter, the test strip for rapid detection of genetically modified products of the present invention will be described in detail with reference to the accompanying drawings.

[0044] The test strip for rapid detection of genetically modified products of the present invention sequentially includes: a sample pad, a gold label binding pad, a nitrocellulose membrane detection area and a water-absorbing pad;

[0045] Colloidal gold-labeled digoxin antibody coated on the gold-labeled binding pad;

[0046] The detection area of ​​the nitrocellulose membrane is provided with a detection line and a quality control line; the detection line is formed by coating streptavidin on the detection area of ​​the nitrocellulose membrane; the quality control line passes on the detection area of ​​the nitrocellulose membrane Formation of coated goat anti-mouse IgG;

[0047] The reaction product of the product to be tested is dropped onto the sample pad and chromatographed toward the absorbent p...

Abstract

The invention discloses a test strip for rapid detection for a transgene product. The test strip comprises a sample pad, a colloidal-gold combination pad, a nitrocellulose membrane detection zone andan absorbent pad; the colloidal-gold combination pad is coated with a colloidal gold-labeled digoxin antibody; the nitrocellulose membrane detection zone is provided with a detection line and a quality control line; the detection line is formed by coating streptavidin on the nitrocellulose membrane detection zone; the quality control line is formed by coating goat anti-mouse IgG on the nitrocellulose membrane detection zone; a reaction product of the product to-be-detected is dropped onto a sample pad, and then is chromatographed in the direction of the absorbent pad through capillary action.

Description

technical field [0001] The invention belongs to the technical field of nucleic acid detection, and in particular relates to a test strip for rapidly detecting transgenic products. Background technique [0002] General transgenic detection is divided into nucleic acid level detection and protein level detection. [0003] Protein level detection (existing colloidal gold protein test paper technology) is convenient for detection, but because some transgenic sample proteins are not expressed and the protein is easily degraded, it is possible that the protein expression in the sample to be tested may not be expressed or the storage conditions of the sample to be tested may cause degradation. Therefore, false negative results are caused (positives are not detected). The protein test strip method has the advantages of rapidity, simplicity, and economy, and does not require any special equipment. However, due to its low detection sensitivity and narrow application range, it is main...
