Aptamers are functional nucleic acids that can specially bind to proteins, peptides, amino acids. nucleotides, drugs, vitamins and other organic and inorganic compounds. The aptamers are identified from random DNA or RNA libraries by a SELEX (systematic evolution of ligands by exponential amplification) process. As aptamers have the advantage, and potential ability to be released from the limitations of antibodies, they are attractive to a wide range of therapeutic and diagnostic applications. Aptamers, with a high-affinity and specificity, could fulfil molecular the recognition needs of various fields in biotechnology. In this work, we reviewed some aptamer Selection techniques, properties, medical applications of their molecules and their biotechnological applications, such as ELONA (enzyme linked oligonucleotide assay), flow cytometry, biosensors, electrophoresis, chromatography and microarrays.

동양달팽이의 EST 서열 4개의 클론을 어셈블리하여 추출되어진 NsCO-I (partial)서열의 코딩 영역은 852 bp, 284개의 아미노산으로 구성되어 있었다. BLAST 결과를 토대로 하여 유사도가 높은 68개의 서열을 추출 하였으며 MEGA6 프로그램을 통해 clustalW 엔진을 통해 다중서열정열을 수행하고 molecular phylogenetic analysis를 수행한 결과 Heterobranchia, Nudibranchia, Cephalaspidea, Sacoglossa, Pulmonata 등의 카테고리별로 잘 분류 되었으며 Mastigeulota kiangsinensis, Helix aspersa, Cepaea nemoralis, Elona quimperiana, Camaena cicatricosa, Cylindrus obtusus 등 육산패류들과 잘 묶인다는 사실을 확인 할 수 있었다.
