Rapid Detection Card for Colloidal Gold in Grapes

Grape Thiamethione Colloidal Gold Rapid Detection Card Instruction Manual

Product number
: YB083C01K

Product Overview

Thiamethione is a new type of nicotine insecticide, which mainly acts on the nervous system of pests. It can selectively bind to the nicotine acetylcholine receptor in insects and block the transmission of insect nerve signals, so as to achieve the effect of killing pests. The insecticide has the advantages of high insecticidal efficiency, strong plant absorption, long effective period, and high crop adaptation safety. It is currently widely used in the control of pests and diseases in grapes and other fruits and vegetables.

The grape-specific thiamethione colloidal gold rapid detection card launched by our company relies on mature immunochromatography technology, which is easy to operate, takes a short time to detect, and the results are intuitive. It can quickly screen grape samples for thiamethione pesticide residues without the need for large-scale precision instruments. It is suitable for a variety of use scenarios such as self-inspection by merchants, enterprise quality inspection, market supervision, and grassroots laboratories.

Second, the detection principle

This product uses
Principle of Competitive Inhibition Immunochromatography
Complete the detection work. After the pretreated grape sample solution to be tested is added dropwise to the sampling area of the detection card, the thiamethione residue in the sample solution will preferentially bind to the specific antibody labeled with colloidal gold, inhibiting the binding reaction between the antibody and the coated antigen on the NC membrane detection line (T-line). The higher the residual content of thiamethione in the sample, the lighter the color of the T-line; vice versa, the darker the color development. The operator can determine whether the thiamethione residue in the grape sample exceeds the standard by comparing the color development depth of the detection line (T-line) and the control line (C-line).

III. Product use

It is specially used for rapid qualitative primary screening of thiamethione pesticide residues in fresh grape samples, and can also be adapted to the screening of thiamethione residues in various fresh fruit and vegetable samples.

IV. Technical indicators

4.1 Minimum detection limit

Minimum detection limit for thiamide in grape samples: 0.01 mg/kg (ppm)

4.2 Cross-reactivity

This product has a trace cross-reaction to similar nicotine insecticides. The specific data are as follows: the cross-reaction rate with imidacloprid is about 1.5%; the cross-reaction rate with furfuran, amidacloprid, thiamethoxam, and domicillin is less than 0.5%. Under normal detection conditions, it will not interfere with the detection results.

V. Kit composition

This product is divided into two specifications: 10 times/box and 20 times/box. The materials contained in the set are as follows:
