Total count of individual sequences over the rounds shown in percentage. Sequencing was performed on ssDNA pools recovered after rounds 2, 6, 7, 8, 9-N and 9-T of SELEX-1 and SELEX-2 and after all rounds of SELEX-3. Additionally, the initial ssDNA library was sequenced to check for biases. R2 to R9-T refer to the specific rounds of SELEX-1, SELEX-2 and SELEX-3 described in Tables 1, 2 and 3, respectively
