Abstract
A nucleic acid aptamer specifically recognizing soluble ST2 protein and its application, belonging to the field of variation or genetic engineering, are described. The technical problem addressed includes how to specifically detect sST2 protein. In order to address this technical problem, nucleic acid aptamers of single-stranded DNA with nucleotide sequences are shown in SEQ ID No. 1-10, respectively. SELEX technology, combined with high-throughput sequencing technology and bioinformatics analysis, reduces the rounds of screening and obtains candidate nucleic acid aptamers, and further analyzes its affinity and specificity to obtain a nucleic acid aptamer that specifically recognizes sST2 protein. The nucleic acid aptamer has the characteristics of high specificity, high stability, convenient synthesis, and easy labeling of functional groups, and the like, and may be used for the detection of sST2 protein and the preparation of biosensors, diagnosis and prognosis of cardiovascular diseases and other products.
