In vitro selection of RNA aptamers to a protein target by filter immobilization.
This unit describes the selection of aptamers from a pool of single-stranded RNA by binding to a protein target. Aptamers generated from this selection experiment can potentially function as protein inhibitors, and may find applications as therapeutic or diagnostic reagents. A pool of dsDNA is used to generate a ssRNA pool, which is mixed with the protein target. Bound complexes are separated from unbound reagents by filtration, and the RNA:protein complexes are amplified by a combination of reverse transcription, PCR, and in vitro transcription.
