preparation example Construction

[0038] The preparation method of the FITC test strip for detecting benzodiazepine mainly comprises the following steps:

[0039] 1) Label the benzodiazepine antibody with FITC and spray it on the conjugate release pad to prepare the conjugate release pad sprayed with FITC-labeled benzodiazepine antibody;

[0040] 2) Spray the hapten-carrier protein conjugate and goat anti-mouse secondary antibody on the reaction membrane as the test line (T) and quality control line (C) to prepare the hapten-carrier coated with benzodiazepine The detection line of protein conjugates and the reaction membrane of the quality control line coated with goat anti-mouse secondary antibody;

[0041] 3) Assemble the conjugate release pad prepared in 1) and 2), the reaction membrane, the sample absorption pad, the water absorption pad and the bottom plate into a test strip.

[0042] The following step-by-step detailed description:

Abstract

An FITC test paper strip for detecting benzodiazepine, a preparing method thereof and an application method of the test paper strip are disclosed. The test paper strip includes a sample absorption pad, a conjugate releasing pad, a reaction film, a water absorbing pad and a bottom plate in order. The conjugate releasing pad is sprayed with an FITC labeled antibody. The reaction film is coated witha hapten-carrier protein conjugate detection line and a goat anti-mouse secondary antibody quality control line. The FITC labeled antibody is utilized to achieve benzodiazepine rapid immunoassay through immunochromatography. The invention also provides the application method for detecting benzodiazepine in a sample by utilizing the test paper strip. The test paper strip has advantages of high sensitivity, capability of accurate quantification, rapid detection, convenient operation, and capability of being practical and economical, and can achieve rapid detection and on-site detection for large-batch benzodiazepine samples.

Description

technical field [0001] The invention relates to the detection of benzodiazepines, in particular to a FITC test strip for quantitatively detecting benzodiazepines by utilizing FITC immunochromatography technology, a preparation method and an application method thereof. Background technique [0002] Benzodiazepines, or amphetamines, are the prototype of a series of synthetic drugs with pronounced stimulant effects on the central nervous system. It is classified as a drug because of the addictive nature of intravenous injection. The adverse reactions caused by benzodiazepines include symptoms such as excessive excitement, restlessness, insomnia, tremor, tension and irritability. Physical tolerance to benzodiazepines develops very quickly, so long-term users must take more and more. The most severe consequence of high doses of benzodiazepines is a toxic neuropathy with symptoms resembling paranoid schizophrenia. Abuse of benzodiazepines often occurs together with abuse of bar...
