Estimating the term…
A high-affinity nucleic acid aptamer for histamine and an aquatic product freshness enzyme sensor, belonging to the technical field of biological detection, is named HIS3-T2 and has a nucleotide sequence shown in SEQ ID NO.2. An application of the high-affinity nucleic acid aptamer for histamine in detecting, separating or enriching the histamine. The aquatic product freshness enzyme sensor includes the following components: an aptamer HIS3-T2, chitopentaose, a nanozyme AuNPs@FeP, and a TMB chromogenic solution. Applications of the aquatic product freshness enzyme sensor in detecting the histamine and in rapidly evaluating freshness of an aquatic product. The present invention further provides a method for rapidly evaluating freshness of an aquatic product. The present invention provides a new biological recognition element for detection of the histamine, which has great significance for the detection and enrichment of the histamine.
