Abstract

The invention provides an immunomagnetic chemiluminescence detection kit for chlorpromazine and an application thereof. The detection kit includes: an enzyme-labeled antigen, an enzyme-labeled antigendiluent, a magnetic-labeled antibody, a magnetic-labeled antibody diluent, a series of chlorpromazine standard substance solutions, a chemiluminescent substrate solution A, a chemiluminescent substrate solution B, a re-dissolving liquid, and a washing liquid, wherein the enzyme-labeled antigen is horse radish peroxidase-labeled chlorpromazine semi-antigen, the magnetic-labeled antibody is immunomagnetic bead-labeled chlorpromazine monoclonal antibody. The invention also discloses a method for detecting residual quantity of the chlorpromazine in animal tissue and milk by means of the detectionkit matching with a chemiluminescence detector. The method is high in sensitivity and specificity and is short in detection time for detection of the chlorpromazine.

Description

technical field [0001] The invention relates to a chemiluminescence detection kit and a detection method thereof, in particular to a magnetic immunochemiluminescence detection kit for detecting residual amounts of chlorpromazine in samples such as animal tissues and milk, belonging to the field of immunological detection. Background technique [0002] Chlorpromazine is a phenothiazine drug, a blocker of central dopamine receptors, acts on the central nervous system, and has various pharmacological effects such as antipsychotic, cooling, antiemetic, hypnotic, and anesthesia. It is mainly used as a sedative in veterinary medicine. In recent years, driven by interests, some people have added chlorpromazine to feed and drinking water privately to achieve the effects of sedation and hypnosis, thereby indirectly promoting fattening and growth; or during transportation, in order to reduce weight loss and stress on the way. In order to prevent the death of meat and prevent the decl...
