Abstract

The invention discloses an indirect-competition-law enzyme linked immunosorbent assay kit for detecting phenylethanolamine A, which comprises a phenylethanolamine A specific antibody, phenylethanolamine A and conjugates and DON-HRP-Conjugated of carrier protein. The indirect-competition-law enzyme linked immunosorbent assay kit for detecting phenylethanolamine A is sensitive, fast and accurate and is mainly used for screening examination of large quantities of samples. Main reagents in the assay kit are all provided in the form of working solution. The indirect-competition-law enzyme linked immunosorbent assay kit for detecting phenylethanolamine A has the advantages of being convenient to use, high in specificity, sensitivity, accuracy and the like and capable of fast detecting residual phenylethanolamine A in feedstuff and animal products.

Description

technical field [0001] The invention relates to the fields of ELISA and veterinary drug residue detection. Specifically, the present invention relates to an enzyme-linked immunosorbent assay kit for detecting phenylethanolamine A. technical background [0002] Phenylethanolamine A, also known as clenrapmine CLRA, is a kind of artificial Synthetic chemicals. Clonpamine, an isomer of formoterol, is Eli Lilly synthesis Ractopamine The by-product of Clenbuterol has the same action and effect as Clenbuterol and Ractopamine. It is a kind of β-agonist and has the effect of nutrient redistribution. It was listed as a substance prohibited from being used in feed and animal drinking water by the Ministry of Agriculture Announcement No. 1519. Phenylethanolamine A and "Clenbuterol" belong to β-adrenoceptor agonists. At the end of 2010, the Ministry of Agriculture announced that it was prohibited Add the substance to drinking water. [0003] Most of the existing detection methods ...
