Definitions for "Aptamer"
DNA or RNA molecule which has been artificially manipulated to allow binding with other molecules and viruses.
A small piece of DNA or RNA engineered to bind to a specific protein. Aptamers can be used in microarray experiments to capture a specific protein from a mixture. Aptamers can be conjugated to other molecules like fluorophores, to allow high-sensitivity detection of proteins, even in very small amounts. See also Fluorophores, Microarray.
a single chain of DNA or RNA that selectively binds to a protein
