Anti-bovine prion protein RNA aptamer containing tandem GGA repeat interacts both with recombinant bovine prion protein and its beta isoform with high affinity.


In order to obtain RNA aptamers against bovine prion protein (bPrP), we carried out in vitro selection from RNA pools containing a 55-nucleotide randomized region to target recombinant bPrP. Most of obtained aptamers contained conserved GGA tandem repeats (GGA)(4) and aptamer #1 (apt #1) showed a high affinity for both bPrP and its beta isoform (bPrP-beta… (More)
