Capture and Release (CaR): a simplified procedure for one-tube isolation and concentration of single-stranded DNA during SELEX†
Abstract
Short biotinylated oligodeoxynucleotides immobilized on streptavidin-coated magnetic beads allow for convenient and rapid purification of single-stranded oligodeoxynucleotides from crude asymmetric PCR mixtures, facilitating the selection of DNA aptamers.
