Embodiment 1

[0065] Embodiment 1, detect the composition of the test paper strip of spectinomycin, streptomycin, gentamycin and neomycin

[0066] 1. Freeze-dried microwell strips with gold-labeled antibodies

[0067] Microwell reagents are housed in the microwell strip, wherein 1 is a microwell strip, and 2 is freeze-dried spectinomycin specific antibody-colloidal gold marker, streptomycin specific antibody-colloidal gold marker, Qingda Microporous reagents for mycin-specific antibody-colloidal gold markers and neomycin-specific antibody-colloidal gold markers;

[0068] The micropore strip that contains micropore reagent has micropore plug 3 ( figure 2 and image 3 );

[0069] The freeze-dried spectinomycin monoclonal antibody-colloidal gold marker, streptomycin monoclonal antibody-colloidal gold marker, gentamicin monoclonal antibody-colloidal gold marker and neomycin monoclonal antibody in the microwell strip Microwell reagents for cloning antibody-colloidal gold markers, the lyophi...

Embodiment 2

[0077] The preparation method of test strip described in embodiment 2, embodiment 1

[0078] 1. Preparation of test strips

[0079] The preparation method of this test strip mainly comprises the steps:

[0080] 1) Prepare freeze-dried spectinomycin monoclonal antibody-colloidal gold marker, streptomycin monoclonal antibody-colloidal gold marker, gentamicin monoclonal antibody-colloidal gold marker and neomycin in microwell strips Monoclonal antibody-colloidal gold-labeled microwell reagents, and cover the microwell strips with microwell plugs.

[0081] 2) Prepare detection lines (T1) coated with spectinomycin-carrier protein conjugates, detection lines (T2) coated with streptomycin-carrier protein conjugates, and coated with gentamicin-carrier protein conjugates. The detection line (T3) of the conjugate, the detection line (T4) coated with neomycin-carrier protein conjugate, and the reaction membrane of the quality control line (C) coated with goat anti-mouse anti-antibody; ...

Embodiment 3

[0160] Embodiment 3, the application of test strip

[0161] One, detect spectinomycin, streptomycin, gentamicin and neomycin in milk with test strip described in embodiment 1

[0162] The test strip of the invention can detect milk samples. The general detection method is as follows:

[0163] 1. Detection method

[0164] Remove the microwell plug covered on the microwell strip, and drop the sample solution to be detected into the microwell strip containing the microwell reagent to obtain a mixed solution 11 of the microwell reagent and sample solution, mix well, and incubate 5min, insert the end of the test paper 12 with the MAX line mark down into the microwell strip, and watch the results within 5min, as shown Figure 7 shown.

[0165] 2. Judgment of test results

[0166] If the content of spectinomycin or streptomycin or gentamycin or neomycin in the sample liquid to be tested is high, the spectinomycin or streptomycin or gentamycin or neomycin in the sample liquid to ...

Abstract

The invention discloses a spectinomycin, streptomycin, gentamycin and neomycin detection test strip and a method thereof. The test strip comprises micro-porous strips, micro-porous reagents, a test paper and micro-porous plugs, the micro-porous reagents are lyophilized colloidal gold labeled spectinomycin, streptomycin, gentamycin and neomycin specific antibodies respectively, the test paper is formed by sequentially connecting a sample absorption pad, a reaction film, a water absorption pad, a protection film and a substrate, the reaction film comprises four detection lines and a quality control line, the four detection lines are coated with a spectinomycin-carrier protein conjugate, a streptomycin-carrier protein conjugate, a gentamycin-carrier protein conjugate and a neomycin-carrier protein conjugate respectively, and the quality control line is coated with an antiantibody. The method for detecting the spectinomycin, streptomycin, gentamycin and neomycin by using the test strip has the advantages of simplicity, rapidness, perceptual intuition, accuracy, portability, wide application range, low cost, and easy popularized use.

Description

technical field [0001] The invention relates to a test strip and a method for detecting spectinomycin, streptomycin, gentamycin and neomycin. Background technique [0002] Spectinomycin, also known as spectinomycin, spectinomycin, spectinomycin, etc., is an aminocycloalcohol antibiotic produced by Streptomyces grandis, which is effective against Gram-negative bacteria (such as Brucella, Kray Bacteria, Proteus, Salmonella, Pasteurella, etc.) have strong effects on Gram-positive bacteria (Streptococcus, Staphylococcus, etc.), and have certain effects on Mycoplasma. It is a new type of special treatment Antibiotics for gonorrhea, which have a strong antibacterial effect on Neisseria gonorrhoeae. It can promote animal growth and is a good animal feed additive. It is widely used in animal husbandry as veterinary medicine. Some unscrupulous traders are driven by economic interests to abuse antibiotics, leaving a large amount of antibiotics in animal products. If you eat animal-d...
