What is an aptamer?

Answer 1

An aptamer is a subsequence of nucleic acid or protein, used to bind to a specific target molecule.

Answer 2

An aptamer is a short, single-stranded DNA or RNA molecule that can bind specifically to target molecules, such as proteins, nucleic acids, or small molecules. Similar to antibodies, aptamers can be used for various applications, including diagnostics, therapeutics, and research purposes. They are selected through a process called Systematic Evolution of Ligands by Exponential Enrichment (SELEX).
