Abstract
A rapid detection method for abrin toxin is provided. The rapid detection method for abrin toxin includes the following steps: reacting an oligonucleotide chain substrate labeled with a fluorescent group and a quenching group, a buffer solution, a BSA solution, a to-be-detected sample and sterile water, incubating at a constant temperature, detecting a fluorescence signal value, and determining whether the abrin toxin exists based on a difference between a change in final fluorescence signal value and a change in final fluorescence signal value of a negative control; where the sample is judged as a positive sample when an average value of the detected final fluorescence signal values is greater than an average value of the final fluorescence signal values of the negative control by +3 times standard deviation. According to the detection method, the direct addition of the sample into the reaction system can reach the sensitivity of 30 ng/mL.
