Problems solved by technology

However, these two methods are complex to operate, prone to false positive results, and cannot be used for high-throughput screening
[0014] 2) In vitro experiments: primary culture of zebrafish liver cells, treatment of cells with test compounds for a period of time, identification of genotoxicity by comet assay (Sun LW, Qu MM, Li YQ, et al, Toxic Effects of Aminophenols on Aquatic Life Using the Zebrafish Embryo Test and the CometAssay.Bull.Environ.Contam.Toxicol., 2004,73: 628-634.), although the test period of this method is short, high-throughput screening can be carried out, but the operation is complicated and there are many false positive results , more importantly, cells do not have drug absorption, distribution, metabolism, and excretion processes in vitro, and the results of the test cannot reflect the real situation of the compound in vivo
[0015] Compared with single-cell gel electrophoresis and comet experiments, the above method has the advantages of low cost, less drug dosage, and simpler operation, but still has the disadvantages of long experimental cycle, complicated operation, poor specificity, and high-throughput Screening, high false positive results

Embodiment 1

[0172] Determination of the optimal developmental stage of zebrafish when the compound of Example 1 is processed

[0173] Embryo collection

[0174] In the early morning, 5 pairs of zebrafish were taken, freely combined and divided into 5 groups to mate and hatch embryos, and 1200 zebrafish were collected, the sediment was sucked out, put into the incubation solution, and incubated in a 28°C incubator. In the middle, take out the white embryo (dead) in time to prevent the water quality from deteriorating, because the zebrafish obtains nutrients through the yolk during this period, so no other nutrients are needed.

[0175] drug treatment

[0176] The zebrafish were divided into 7 experimental groups, which were 1 day, 2 days, 3 days, 4 days, 5 days, 6 days, and 7 days after fertilization. Each experimental group was divided into three groups, blank group, 0.1% dimethyl sulfoxide (DMSO) negative control group and experimental treatment group (50 μ M staurosporine (staurospori...

Embodiment 2

[0184]Embodiment 2 compound processes the mensuration of optimal length of time

[0185] Embryo collection

[0186] In the early morning, 5 pairs of zebrafish were taken, freely combined and divided into 5 groups to mate and hatch embryos, and 1200 zebrafish were collected, the sediment was sucked out, put into the incubation solution, and incubated in a 28°C incubator. In the middle, take out the white embryo (dead) in time to prevent the water quality from deteriorating, because the zebrafish obtains nutrients through the yolk during this period, so no other nutrients are needed.

[0187] drug treatment

[0188] Zebrafish were divided into five experimental groups, each group including blank group, treatment group (50 μM staurosporine (staurosporine), 0.1% dimethyl sulfoxide (DMSO) dissolved) and negative control group (0.1% dimethyl sulfoxide (DMSO) sulfoxide (DMSO)). The experimental groups were treated 2 days after zebrafish fertilization, and the treatment time was 6 ...

Embodiment 3

[0196] The detection of embodiment 3 drug genotoxicity

[0197] Embryo collection

[0198] In the early morning, 10 pairs of zebrafish were taken, freely combined and divided into 10 groups to mate and hatch embryos, 1200 zebrafish were collected, the sediment was sucked out, put into the incubation solution, and incubated in a 28°C incubator. In the middle, take out the white embryo (dead) in time to prevent the water quality from deteriorating, because the zebrafish obtains nutrients through the yolk during this period, so no other nutrients are needed.

[0199] drug treatment

[0200] The zebrafish were divided into eight experimental groups, respectively 0.1, 1, 10, 100, 1000 μ M genotoxic drug cisplatin (cisplatin), and then dissolved in the hatching solution according to the above concentration; the blank group was no treatment, 0.1% di Methyl sulfoxide (DMSO) negative control group, 50 μM staurosporine (staurosporine) positive control group that can cause genotoxicity...

Abstract

The invention relates to a method for carrying out enzyme-linked immunoadsorption detection on an integral zebra fish and application of the method in drugs for identifying genotoxic compounds, screening anti-tumor drugs and repairing DNA damage. On one hand, the invention can be used for evaluating the genotoxicity of the compounds including environmental compounds, drugs, cosmetics, food additives and the like, and on the other hand, the invention can be used for screening new drugs, such as the anti-tumor drugs, antioxidants, anti-aging drugs, anti-neurodegenerative disease drugs and the like. The invention has very important guiding significance on diagnosing and treating certain diseases and novel drug research and development and compound toxicity screening. By applying the zebra fish to evaluate the compound toxicity and screen the novel drugs, the advantages of low cost, low use level of samples, automatic operation and the like can be achieved, and an in vivo physiological environment of a live animal can be provided, therefore, the goals of simple and convenient evaluating and screening works, rapidness, economy, high efficiency and high flux can be achieved.

Description

technical field [0001] The present invention relates to an enzyme-linked immunosorbent assay, more specifically, to a method for performing enzyme-linked immunosorbent assay on whole zebrafish, and the method is useful in identifying genotoxic compounds, screening anti-tumor drugs, and repairing DNA damage application in medicines. Background technique [0002] Genotoxicity refers to direct or indirect cellular DNA damage. DNA is an important biomacromolecule that has the function of transmitting genetic information in cells, and is an important research object of biochemistry and molecular biology. The DNA molecule is composed of two antiparallel polynucleotide chains through the principle of base pairing to form a double helix structure, and the genetic information carried by it is determined by the type, quantity and arrangement order of the bases on the polynucleotide chain. The sequence is hidden deep inside the DNA double helix. The double helix structure composed of...
