NA If the oligo is a known aptamer sequence: For binding studies, perform a refolding protocol to ensure proper function (i.e. binding to antigen or target). Refer to the aptamer reference source for the appropriate refolding parameters and binding conditions. Note: it is unknown whether aptamer functions properly without refolding.
In the presence of E. coli CEM, aptamer adopts an active conformation and cleaves the adenosine ribonucleotide residue, separating fluorescein from the dabcyl quencher.
nnn in structure represents (fluorescein-dT)-adenosine ribonucleotide - (dabcyl-dT).
