Abstract
A rapid detection method for ricin toxin is provided. The rapid detection method for ricin toxin comprises reacting an adenine-containing 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 ricin toxin exists based on a difference between an average value of final fluorescence signal values and an average value of final fluorescence signal values of a negative control; wherein the sample is judged as a positive sample when the average value of the detected final fluorescence signal values is greater than the average value of the final fluorescence signal values of the negative control by +3 times standard deviation.
