summary

Melamine
(Melamine, MEL) is a triazine nitrogen-containing heterocyclic organic compound. It is used as a chemical raw material and cannot be used in food processing or food additives. Long-term or repeated intake of melamine may affect the kidneys and bladder, resulting in stones. Melamine is also a metabolite of the insecticide cyclopromazine in animals and plants. This product is suitable for rapid on-site testing in enterprises, testing institutions, supervision departments and other fields.

Detection principle

This product adopts the principle of competitive inhibition immunochromatography. The melamine in the sample binds to the specific antibody labeled with colloidal gold, inhibiting its and
NC film inspection

line survey
The binding of the antigen on the (T-line) leads to a change in the color depth of the detection line. Whether the sample contains the substance to be tested or not, the quality control line (C-line) will

Color development to show that the detection is valid. This product can be matched with a colloidal gold analyzer for detection at the same time, extract sample detection data, and obtain the final detection result after data analytics.
