Abstract

The invention discloses an apparatus for aided detection of the existence of a transgenic protein in a food. The apparatus comprises: a first porous plate body; a sample adding device comprising a second porous plate body, a cone and a plurality of sample adding channels, wherein the diameter of the cone gradually decreases from bottom to top, the free end of the cone forms a sample adding hole, the plurality of sample adding channels correspond to pores in the second porous plate one to one, one ends of the plurality of sample adding channels are connected with the sample adding holes, and the other ends the plurality of sample adding channels are connected with the pores in the second porous plate; and hollow fiber polypropylene membrane tubes arranged between the first porous plate body and the second porous plate body, wherein the inner wall of every hollow fiber polypropylene membrane tube is attached with an antibody specifically binding to a transgenic protein to be detected, the upper ends of the hollow fiber polypropylene membranes tubes are fixed in the pores of the second porous plate body, the lower ends of the hollow fiber polypropylene membrane tubes are fixed in the pores of the first porous plate body, and the inner wall of every hollow fiber polypropylene membrane tube is provided with a plurality of projections and recesses.

Description

technical field [0001] The invention relates to a device for assisting in detecting whether there is transgenic protein in food. Background technique [0002] One or several exogenous genes are transferred to a specific organism through genetic engineering technology, and the corresponding products (polypeptides or proteins) are effectively expressed. This process is called transgenesis. Foods processed from GMOs are genetically modified foods. According to the different sources of genetically modified food, it can be divided into plant genetically modified food, animal genetically modified food and microbial genetically modified food. Genetically modified food has many advantages: it can increase crop yield; it can reduce production cost; it can enhance the ability of crops to resist insect pests and viruses; it can improve the storability of agricultural products. The safety evaluation of GMOs is the prerequisite for the marketization and commercialization of GMOs and th...
