A kind of Determination of Multiple Pesticide Residues in Vegetables test strip based on Broad specificity antibody identification, which includes PVC bottom plate, sample pad, gold-labelled pad, detection line, nature controlling line, nitrocellulose membrane, water absorption pad；The organophosphorus pesticide wide spectrum antibody, carbamates wide spectrum antibody and pyrethroid pesticide wide spectrum antibody mixture of colloid gold label are coated in the gold-labelled pad；The detection line is coated with the general antigen of organophosphorus pesticide, the general antigen of carbamates and the general antigen of pyrethroid pesticide；Rabbit anti-mouse igg antibody is coated on the nature controlling line.By the control of the details factors to test strips, close to the isoelectric point of detected pesticide protein, so that it be made to form stronger conjugate with antigen.The test strips can detect organophosphorus pesticide most of in the agricultural product such as veterinary antibiotics, carbamate chemicals for agriculture and pyrethroid pesticide, visual phenomenon, high sensitivity. |
