Phenylmethoxazole Colloidal Gold Rapid Detection Card Instruction Manual

Phenethylmethoxazole Colloidal Gold Rapid Detection Card Instruction Manual

Product Number: YB001C01K

Summary

Difenoconazole (Difenoconazole) belongs to triazole fungicides, the main function is to inhibit the formation of tubulin in the mitotic process of fungi, widely used in fruit trees, vegetables and other crops, effective prevention and treatment of black star disease, black bean disease, white rot, spot defoliation, red disease, etc.

Detection Principle

This product adopts the principle of competitive inhibition immunochromatography, the specific antibody of phenethylmethylmethoxazole in the sample binds to the colloidal gold-labeled antibody, which inhibits the binding of the antibody to the antigen on the NC film detection line (T-line), resulting in the change of the color depth of the T-line; according to the T-line and the quality control line (C-line) color depth judgment result.

Scope of application

This product is suitable for qualitative detection of phenylmethoxazole residues in fresh vegetables, fruits and other samples.

Note: The types of test samples refer to the national standard GB2763.

Precautions

(1) Tools such as knives, scissors, and stickers for processing samples before testing should be cleaned to avoid cross-contamination.

(2) Sample requirements: Avoid spoilage and deterioration of samples; avoid large pieces of soil (can be thrown off or wiped with other clean items).

(3) Before testing, it is recommended that the sample be fully stirred and mixed (if there is less sampling, a representative part should be taken and then weighed), so that the test results can more realistically reflect the actual drug residue of the sample.

(4) The test environment temperature should be controlled at 20~ 30 ° C. Too high or too low temperature will affect the test results.

(5) Please follow the test steps for testing. Do not touch the color-developing area of the test strip during operation to avoid direct sunlight and direct blowing of electric fans.

(6) The sample solution to be tested needs to be clarified, otherwise it will easily lead to abnormal phenomena such as insignificant color development, which will affect the determination of experimental results.

(7) Products that have expired or damaged aluminum foil bags cannot be used. Please use the test card immediately after unpacking.

(8) Please use the sample as soon as possible after processing. If the time is too long, you need to reprocess the sample for re-testing.

(9) When a positive result appears, it is recommended to retest. The test results of this product are for reference only. If you need to confirm, please refer to the relevant national standards and methods.

(10) When adding a standard for verification, the standard solvent generally chooses methanol, and the final sample is recommended to add 10-50 μL of scalar.

(11) When directly testing the standard, the solvent should be used to match the extract of the kit. The amount of organic solvent added is controlled within 1%. Tap water, distilled water, purified water or deionized water cannot be used as a negative control.

Safety instructions

(1) The experiment should match the corresponding experimental equipment and wear the necessary experimental equipment (white clothes, gloves, masks, etc.).

(2) The test kit should be properly stored. Please put it in a place that is not easy for children to contact.

(3) After the experiment, keep the laboratory clean and the air flow of the experimental environment.

(4) This product is a disposable product. After the test is completed, it should be properly disposed of. The experimental waste should be collected separately. It is recommended to dispose of it according to the medical waste.

(5) The reagents involved in this product are safe and reliable, and do not contain carcinogenic, highly toxic, flammable, explosive, and highly corrosive reagents, but should not be eaten.

storage conditions and valid period

(1) Original packaging: Store dry at 2-30 ° C in the dark, do not freeze, valid period 12 months.

(2) After unpacking: Use the test card immediately after unpacking, do not freeze.
