List of oligonucleotides used in this work

Name of the sequence	Sequence (5′ to 3′)a)
Ochratoxin A aptamer	TGGTGGCTGTAGGTCAGCATCTGATCGGGTGTGGGTGGCGTAAAGGGAG CATCGGACA ACG
dA‐Complementary sequence (dA‐cOligo)	AAAAAAAAAAAAAAAAAAAAAAAAA‐TA‐TGTCCGATGC
Random sequence	NH2‐C12‐TGGACCCCCTC
Forward primer	TGGTGGCTGTAGGTCA
Reverse primer	CGTTGTCCGATGCTC
dT	TTTTTTTTTTTTTTTTTTTTTTTTT‐C6‐dT‐NH2

Underlined bases correspond to primer binding regions. Italics bases indicate complementary sequences within the aptamer and oligonucleotides. In dA‐cOligo, TA was used as a spacer between d(A)₂₅ region and complementary sequence.
