Abstract

A synthetic library of ca. 10(13) single stranded oligodeoxynucleotides, each comprising a randomized 40mer sequence and homogeneous 10mer flanking regions, was screened for binding to recombinant human 14-3-3gamma. A single aptamer, which showed similar affinities (K(D) approximately 10(-8)M) for six isoforms of the protein, has been shown to bind to undenatured 14-3-3 protein in the cerebral spinal fluid of scrapie infected sheep.
