Embodiment 1

[0027] This embodiment relates to an encrypted lateral flow gold-labeled immunochromatographic detection card and detection method for rapid detection of residual penicillin in milk.

[0028] Encrypted lateral flow gold-labeled immunochromatographic detection card: two detection channels are integrated on one card, namely the gold-labeled immunochromatographic detection channel of penicillin and the gold-labeled immunochromatographic detection channel of bovine lactoferrin, of which cow milk The detection of ferritin is used to judge the authenticity of the samples. The order of the two detection channels is randomized. Paste a QR code on one side to identify the test card, such as figure 1 shown.

[0029] Rapid detection using an encrypted lateral flow chromatography test card, including the following steps:

[0030] (1) Add 150 μL of the milk sample to be tested dropwise into the sample hole of the test card, and let it stand for chromatography for 15 minutes to obtain th...

Embodiment 2

[0037] This embodiment relates to an encrypted lateral flow latex chromatography detection card and detection method for combined rapid detection of swine fever and heavy metal lead.

[0038] Encrypted lateral flow latex chromatography detection card: two detection channels are integrated on one card at the same time, namely the latex chromatography detection channel of swine fever virus and the latex chromatography detection channel of heavy metal lead. The order of the two detection channels is randomized. Stick a barcode on one side to identify the test card, such as figure 2 shown.

[0039] Rapid detection using an encrypted lateral flow chromatography test card, including the following steps:

[0040] (1) Add 150 μL of the porcine serum to be tested dropwise into the sample hole of the test card, and let it stand for chromatography for 15 minutes to obtain the chromatographic test card to be tested.

[0041] The latex chromatography detection of swine fever virus adop...

Embodiment 3

[0046] This embodiment relates to a test card and a detection method for the detection of genetically modified crops, specifically an encrypted lateral flow nucleic acid chromatography detection card and a detection method for the rapid detection of the Bt toxin gene in rice.

[0047] Encrypted lateral flow nucleic acid chromatography detection card: 2 detection channels are integrated on one card at the same time, which are the nucleic acid chromatography detection channel of the Bt toxin gene and the auxiliary chromatography detection channel.

[0048] The detection channel of the Bt poisonous protein gene is the molecular probe of the Bt toxic protein gene at the T line, and the molecular probe of the SPS gene (rice sucrose phosphate synthase gene, which exists in all rice) at the C line. The auxiliary chromatography detection channel is divided into two types: one is the SPS gene molecular probe at the T line and the C line; the other is the blank at the T line, only the SP...

Abstract

The invention discloses an encrypted lateral flower chromatography detection card and a detection method. The detection card is mainly characterized in that a plurality of lateral flow chromatography detection channels are integrated on one detection card at the same time, a kind sorting sequence of a detection object corresponding to each channel has randomness, and a user cannot directly read a detection result by naked eyes. Each detection card has a unique identification code which is applied to card identity authentication and contains decryption information of all detection channels. A card reader can send the identification code and original detection signals of all the channels to a network server through the internet to be encrypted, and detection data can be passed back to the card reader through the network to be displayed and outputted.

Description

technical field [0001] The invention belongs to the field of biological analysis and detection, and more specifically relates to an encrypted lateral flow chromatography detection card and a detection method. Background technique [0002] Immunochromatography test paper card is a rapid immunoassay method combining immunological technology and chromatographic technology. After one end of the protein is immersed in the sample, the sample will move forward along the membrane due to capillary action. When moving to the area where the antibody is immobilized, the corresponding antigen in the sample will specifically bind to the antibody. If immunocolloidal gold or Immunoenzyme staining can make the region display a certain color, or use magnetic particles as a marker to detect magnetic signals in the region, thereby achieving specific immunodiagnosis. Among them, colloidal gold-labeled immunochromatography technology is simple, fast, accurate, and highly sensitive, and is the mo...
