The recovery rate and the products of each SELEX selection round for ABL aptamer. (a) The recovery rate of each SELEX round. After 13 rounds of screening, with the increase of the number of screening rounds, the recovery rate was increasing overall and tended to be stable. (b) Verification of the products of each SELEX round by PCR, M 50 bp DNA ladder; 1–13: SELEX round numbers.
