Aptamers from Cell-based Selection for Bioanalysis and Bioimaging

As a new type of molecular recognition probe, aptamers from Cell-SELEX possess high binding affinity and specificity toward target cells. They have many superiorities over antibodies, including easy synthesis, convenient modification, high chemical stability, and low immunogenicity. All these advantages make them excellent alternatives to antibodies in bioanalytical applications, indicating high potential for precise tumor theranostics.
